Tech Company Interview Guides: How 40+ Top Companies Actually Interview

Most candidates prepare for "the tech interview" as if it were one thing. It is not. At Airbnb, a values interviewer from outside your team can veto an offer regardless of technical performance. At Cursor, the deciding round is a paid eight-hour project in the company's real codebase, with AI tools encouraged. At Shopify, the signature interview is a chronological walk through your entire life. At Databricks, the round that eliminates prepared candidates is live multi-threaded programming. Jane Street will talk you out of using OCaml; Anthropic will tell you exactly when you may and may not use Claude; Ramp hides a puzzle in the job application itself.

Interviews differ more by company than by role, and preparing for the specific company you face is the highest-leverage work you can do after fundamentals. This guide collects our detailed, research-backed interview guides for 60 top technology companies, organized by sector, with what makes each loop distinctive and links to the full round-by-round breakdowns.

How These Guides Are Organized

For each company, we cover up to four dimensions of the interview:

• The interview process, round by round: every stage from recruiter screen to offer, with formats, timelines, and the rounds unique to that company.
• Behavioral interview questions: what the company actually screens for culturally, the questions candidates report, and worked sample answers in that company's register.
• The system design interview: the reported prompts, what interviewers probe, and a walkthrough of a signature design problem.
• How to answer "Why do you want to work here?": what interviewers listen for in the motivation question, with a full sample answer and the mistakes that sink candidates.

Use them together: read the process guide first to map your loop, then prepare each round with its dedicated guide.

AI Labs and AI Infrastructure

The frontier AI companies run the most distinctive interviews in tech, from mission screening to work-sample projects, and their policies on using AI during interviews now vary wildly: know your company's rules before you walk in.

Anthropic

Anthropic's loop pairs practical, implementation-heavy coding with an explicit values interview that sinks more strong engineers than any technical round. Its official AI policy is widely misreported: you may refine your application with Claude, but live interviews and most take-homes are AI-free.

• Top Anthropic behavioral interview questions
• What to expect in the Anthropic system design interview
• How to answer "Why do you want to work at Anthropic?"

OpenAI

OpenAI publishes its own grading bar (well-designed solutions, high-quality code, performance, test coverage) and may run system design twice in one loop. Product-flavored design prompts expect full-stack answers: wireframes, API contracts, and schemas, not just backend boxes.

• Top OpenAI behavioral interview questions
• What to expect in the OpenAI system design interview
• How to answer "Why do you want to work at OpenAI?"

xAI

xAI moves from first call to offer in two to three weeks, requires a "Statement of Exceptional Work" at application, and ends many loops with a presentation of a project you owned. There is no dedicated behavioral round; ownership and autonomy are probed inside technical conversations.

• What is the xAI interview process like? (round by round)
• Top xAI behavioral interview questions
• What to expect in the xAI system design interview
• How to answer "Why do you want to work at xAI?"

Google DeepMind

DeepMind is really three loops: Google-style for software engineers, ML-depth with paper presentations for research engineers, and research discussions for scientists. Interviews are strictly AI-tool-free, and the hiring committee alone can take three to four weeks.

• What is the Google DeepMind interview process like? (round by round)
• Top Google DeepMind behavioral interview questions
• What to expect in the Google DeepMind system design interview
• How to answer "Why do you want to work at Google DeepMind?"

Perplexity

Perplexity averages about 23 days from application to offer and ends with a founder interview. Every system design question orbits AI search: RAG, retrieval, crawling freshness, and the cost-latency-quality triangle.

• What is the Perplexity interview process like? (round by round)
• Top Perplexity behavioral interview questions
• What to expect in the Perplexity system design interview
• How to answer "Why do you want to work at Perplexity?"

Scale AI

Scale's loop includes a signature debugging round in an unfamiliar multi-file codebase against the clock, and its recruiters openly screen for comfort with a high-intensity culture. Post-Meta-deal, the "why Scale, why now" question is a genuine filter.

• What is the Scale AI interview process like? (round by round)
• Top Scale AI behavioral interview questions
• What to expect in the Scale AI system design interview
• How to answer "Why do you want to work at Scale AI?"

Cursor (Anysphere)

Cursor's decision round is unlike anything else in tech: a paid, roughly eight-hour project inside Cursor's actual codebase, with AI tools explicitly encouraged, followed by a review where you defend every line. Using AI badly is the fastest reported way to fail.

• What is the Cursor interview process like? (round by round)
• Top Cursor behavioral interview questions
• What to expect in the Cursor system design interview
• How to answer "Why do you want to work at Cursor?"

Databricks

Databricks runs one of the hardest engineering loops in the industry, headlined by a concurrency round (live multi-threaded programming) with a reputation for eliminating FAANG-prepared candidates. Its behavioral round maps one to one onto six published values.

• Top Databricks behavioral interview questions
• What to expect in the Databricks system design interview
• How to answer "Why do you want to work at Databricks?"

Mistral AI

Europe's frontier lab runs one of AI's fastest loops (about two weeks) with two unusual rounds: a structured LLM quiz with expected answers on transformer internals and KV caching, and a review round correcting a deliberately messy pull request. Some coding rounds ask you to implement multi-headed attention from scratch.

• How to answer "Why do you want to work at Mistral AI?"
• What is the Mistral AI interview process like? (round by round)
• Top Mistral AI behavioral interview questions
• What to expect in the Mistral AI system design interview

Cohere

The enterprise-first lab tests production ML code (write tests, run your solutions: recited LeetCode answers get flagged) and, unusually among AI labs, runs a genuine dedicated behavioral round. System design centers on multi-tenant model serving: cost-per-query, GPU scheduling, and tenant isolation.

• How to answer "Why do you want to work at Cohere?"
• What is the Cohere interview process like? (round by round)
• Top Cohere behavioral interview questions
• What to expect in the Cohere system design interview

Hugging Face

The open-source ML company hires like an open-source project: no LeetCode, two to three conversations plus a take-home built on real problems the company is working on, presented and defended afterward. Your public GitHub and Hub activity function as a standing portfolio, and the cover letter genuinely matters.

• How to answer "Why do you want to work at Hugging Face?"
• What is the Hugging Face interview process like? (round by round)
• Top Hugging Face behavioral interview questions
• What to expect in the Hugging Face system design interview

ElevenLabs

The AI-audio company wants "founders who happen to be looking for a job": its behavioral round is a deep dive into projects you led or created, and its signature product decomposition round has you design the user experience and the system together for a voice-product use case.

• How to answer "Why do you want to work at ElevenLabs?"
• What is the ElevenLabs interview process like? (round by round)
• Top ElevenLabs behavioral interview questions
• What to expect in the ElevenLabs system design interview

Groq

AI sector at a glance:

Big Tech

The established giants run the most structured loops, and each has a cultural rubric worth knowing by name: Microsoft scores growth mindset, Netflix applies the keeper test, Nvidia screens for resilience to blunt criticism.

Apple

Apple's process is decentralized: each team designs its own loop, and behavioral evaluation is woven through every round rather than isolated. The consistent bar: craft, low ego, comfort with secrecy, and a real opinion about an Apple product.

• Top Apple behavioral interview questions
• How to answer "Why Apple?"
• Top Apple system design interview questions
• What is asked in the second round of an Apple interview?

Microsoft

Microsoft interviewers are trained to score behavioral answers against growth mindset and named competencies, including inclusion as an explicit dimension. Use STAR, then add what you learned: their rubric rewards the learning step specifically.

• Top Microsoft behavioral interview questions
• What questions are asked in a Microsoft interview?
• What to expect in a Microsoft technical interview
• Top Microsoft system design questions

Netflix

Netflix is the one company where the culture interview can override strong technical performance: roughly half the evaluation is alignment with the published Culture Memo, and the keeper test sits behind every round. Study the memo like a syllabus, because it is one.

• Top Netflix behavioral interview questions
• The Netflix interview process for software engineers
• Top Netflix system design interview questions

Nvidia

Nvidia hires by team, and interviews flow almost entirely from that team's actual work, with post-onsite waits of five-plus weeks commonly reported. The behavioral screen is shaped by a famously blunt culture: how you receive hard, public criticism is the centerpiece probe.

• What is the Nvidia interview process like? (round by round)
• Top Nvidia behavioral interview questions
• How to answer "Why do you want to work at Nvidia?"
• Top Nvidia system design interview questions

Tesla

Tesla schedules the hiring manager conversation before any technical screen, grills fundamentals from first principles, and increasingly asks finalists for an "Evidence of Excellence" write-up of their best work. Expect a bar comparable to Google at a much faster tempo.

• What is the Tesla interview process like? (round by round)
• Top Tesla behavioral interview questions
• Why work for Tesla?
• Top Tesla system design interview questions

Adobe

Adobe's assessment mixes coding with CS-fundamentals multiple choice (where unprepared candidates bleed points), and its design rounds span three altitudes: product architecture, object-oriented design, and database judgment. Behavioral evaluation runs on two lenses: own the outcome, create the future.

• What is the Adobe interview process like? (round by round)
• Top Adobe behavioral interview questions
• What to expect in the Adobe system design interview
• Why join Adobe?

LinkedIn

LinkedIn grades communication and tradeoff narration as explicitly as code, and its design prompts are product-centric graph problems: feed, notifications, People You May Know. The members-first value generates its most distinctive behavioral probe: user trust versus growth metrics.

• How to answer "Why do you want to work at LinkedIn?"
• Top LinkedIn behavioral interview questions
• What to expect in the LinkedIn system design interview
• The interview process at LinkedIn

Oracle

Oracle is several companies in one (OCI, database, applications), and loops differ accordingly; timelines run four to eight weeks, and the distinctive Bartender round brings an outside-team interviewer to calibrate the bar, like Amazon's Bar Raiser.

Consumer, Marketplace, and Commerce

Consumer companies interview through their product realities: marketplace tradeoffs at Uber and DoorDash, values-as-veto at Airbnb, a biography instead of a behavioral round at Shopify.

Uber

Uber runs a dedicated bar-raiser-style behavioral round scored against its published values, and its most distinctive question shape is the marketplace tradeoff: two groups with opposite interests, and your reasoning between them.

• Top Uber behavioral interview questions
• Top Uber system design interview questions

Reddit

Reddit's motivation question has a built-in authenticity check ("which communities are you active in?"), and candidates with a genuine history on the platform, moderators especially, hold an advantage nothing else replicates.

• How to answer "Why do you want to work at Reddit?"
• What is asked in the second round of a Reddit interview?

Duolingo

Duolingo runs two engineers in every technical round (one interviewing, one shadowing) and evaluates real engineering sense and product thinking over hard LeetCode, through an onsite of pair programming, code review, and a coffee chat that is not a break. Python is the standardized house language, and genuine product usage (a real streak) pays off in every round.

• How to answer "Why do you want to work at Duolingo?"
• What is the Duolingo interview process like? (round by round)
• Top Duolingo behavioral interview questions
• What to expect in the Duolingo system design interview

Roblox

Roblox's online assessment is the most unusual in big tech: about two hours combining coding, proprietary game-based challenges, and a built-in 25-minute behavioral section, with a Bar Raiser round closing the loop. Everything calibrates against its precisely stated value hierarchy: community before company, company before team, team before individual.

• How to answer "Why do you want to work at Roblox?"
• What is the Roblox interview process like? (round by round)

Consumer and marketplace at a glance:

Fintech and Quantitative Finance

Money changes the interview: idempotency, reconciliation, and incident ownership are assumed vocabulary, and the elite quant firms could not be more different from one another.

Stripe

Stripe's loop simulates real work: an integration round with a real repo, API docs, and full internet access; a debugging round in unfamiliar code; and a rare dedicated API design round. Behavioral interviewers are calibrated to filter polished-but-vague answers fast.

• What is the Stripe interview process like? (round by round)
• Top Stripe behavioral interview questions

Ramp

Ramp hides a small CTF puzzle in the application, runs a four-level progressive coding assessment where early architecture determines late survival, and averages eleven days to offer. It hires "tiny CEOs" and asks for your controversial opinions, plural.

• How to answer "Why do you want to work at Ramp?"
• What is the Ramp interview process like? (round by round)
• Top Ramp behavioral interview questions
• What to expect in the Ramp system design interview

Citadel

Citadel's HackerRank assessment fails suboptimal solutions on hidden tests, its onsite pushes from correct toward optimal toward the constant factors, and its design rounds run on microsecond budgets: order books, feed handlers, and mechanical sympathy.

• How to answer "Why do you want to work at Citadel?"
• What is the Citadel interview process like? (round by round)
• Top Citadel behavioral interview questions
• What to expect in the Citadel system design interview

Jane Street

Jane Street's onsite is three to four 70-minute paired rounds extending one evolving problem, and the folklore is wrong twice: SWE candidates need neither OCaml nor probability drills. Honesty is structural: they ask you to disclose if you have seen a problem before.

• How to answer "Why do you want to work at Jane Street?"
• What is the Jane Street interview process like? (round by round)
• Top Jane Street behavioral interview questions
• What to expect in the Jane Street system design interview

Two Sigma

Precise, calibrated communication is graded throughout.

• How to answer "Why do you want to work at Two Sigma?"
• What is the Two Sigma interview process like? (round by round)
• Top Two Sigma behavioral interview questions
• What to expect in the Two Sigma system design interview

Bloomberg

Bloomberg's loop is famous for two things: the tagged practice-question pool genuinely reflects its interviews, and candidates who solve everything perfectly still get rejected on weak "why Bloomberg" answers: genuine interest is offer-deciding. The system design round (real-time market data, conflation, entitlements) is consistently reported as the hardest.

• How to answer "Why do you want to work at Bloomberg?"

Dev tools and enterprise at a glance:

Defense and Frontier Tech

The defense and hard-tech companies add dimensions nothing else has: at Anduril and SpaceX, mission conviction is screened in every round and ambivalence is a detectable, disqualifying trait; at Waymo, the same seriousness attaches to safety mindset and self-awareness.

Anduril

Anduril screens for genuine motivation to build defense technology from the first recruiter call, asks pointed product questions ("what is your least favorite Anduril product?"), and runs deliberately ambiguous technical prompts where requirements-extraction is graded. Most roles require US person status.

What These 60 Loops Have in Common (and Where They Diverge)

Researching these companies side by side surfaces patterns worth knowing before you prepare for any of them:

1. Practical coding is displacing puzzle coding. Stripe, GitHub, Canva, Shopify, Ramp, Jane Street, xAI, DoorDash, Vercel, Discord, Intuit, ElevenLabs, and Hugging Face all evaluate through realistic work: take-homes, pairing, debugging, code review, and build-a-feature rounds. Pure LeetCode preparation now covers a shrinking fraction of the market; pattern fluency still matters everywhere, but shipping clean, tested code under narration matters more. Grokking the Coding Interview builds the pattern base that transfers across all of these formats.
2. Behavioral rubrics are increasingly published. Netflix's memo, Atlassian's and Canva's named values, ByteDance's ByteStyle, Databricks' principles, Amazon-style calibration rounds at Oracle and Uber: more companies than ever tell you exactly what they score. The preparation is mechanical once you know that: map evidence-dense stories to the named values. Grokking Modern Behavioral Interview covers the method.
3. System design is diverging by domain. Fintech rounds assume idempotency and reconciliation; consumer rounds assume feed fan-out and caching; AI companies assume RAG and GPU economics; enterprise companies assume multi-tenancy and upgrade safety. The core method transfers (Grokking the System Design Interview, with Grokking System Design Fundamentals for the building blocks and Advanced System Design Interview, Volume II for depth), but the last mile is company-specific, which is what the guides above are for.
4. AI-use policies now define interviews. The spread is remarkable: DeepMind and Anthropic run AI-free rounds; Shopify and DoorDash allow tools with verification; Cursor requires skilled AI use and fails candidates who paste without judgment; and Rippling makes tools optional but grades you against a different rubric depending on your choice. Always confirm your company's policy, and if AI is allowed, practice the verify-everything workflow beforehand. For AI-fluency itself, Grokking Modern AI Fundamentals covers the vocabulary that now threads through interviews everywhere.
5. Timelines range from 11 days to 10 weeks. Ramp, xAI, Mistral, and Perplexity move in days-to-weeks; DeepMind, Oracle, Roblox, and Nvidia stretch toward two months or beyond. Sequence your pipeline deliberately: start slow processes first, and expect the fast companies to force decisions.

FAQ

How long does a tech company interview process take? Anywhere from 11 days (Ramp) to 10 weeks (Google DeepMind), with 3 to 6 weeks the industry median. Committee-based companies (Google, DeepMind, Oracle) and team-matching-heavy ones (Nvidia) run longest; founder-led startups (Perplexity, xAI, Cursor) run fastest.

Do all companies ask system design questions? Almost all do for mid-level and senior roles, but the format varies: classic architecture rounds (most big tech), domain-specific design (Citadel's order books, Perplexity's RAG pipelines), decomposition of vague problems (Palantir), or design questions embedded inside coding rounds (Jane Street, Ramp).

How different are behavioral interviews really? Substantially. Netflix's culture round can veto a technically perfect performance, Airbnb's values interviews are run by trained outside interviewers, xAI has no behavioral round at all, and Shopify replaces the whole genre with a life-story conversation. Read the company-specific guide before recycling your standard stories.

Should I use AI tools during interviews? Only where explicitly permitted, and skillfully where required. Policies now range from strict bans (DeepMind, Anthropic's live rounds) to active encouragement with accountability (Cursor, Shopify). Using AI where banned ends candidacies; using it clumsily where encouraged does too.
