Tech Company Interview Guides: How 134 Top Companies Interview

Most candidates prepare for "the tech interview" as if every company runs the same one. They do not. At Airbnb, a values interviewer from outside your team can veto an offer, even after strong technical rounds. At Cursor, the deciding round is a paid project of about eight hours in the company's real codebase, with AI tools encouraged. At Shopify, the signature interview is a chronological walk through your whole life. At Databricks, the round that removes prepared candidates is live multi-threaded programming. Jane Street will tell you not to use OCaml. Anthropic will tell you exactly when you may and may not use Claude. Ramp puts a small puzzle inside the job application itself.

Interviews differ more by company than by role. After the fundamentals, the most useful preparation is studying the specific company you face. This guide collects our research-backed interview guides for 134 top technology companies, grouped by sector. Each entry explains what makes that company's loop (its full sequence of interview rounds) distinctive. Each entry also links to the full round-by-round breakdowns.

How These Guides Are Organized

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

• The interview process, round by round: every stage from recruiter screen to offer. It lists formats, timelines, and the rounds unique to that company.
• Behavioral interview questions: what the company screens for culturally, the questions candidates report, and worked sample answers in that company's style.
• The system design interview: the reported questions, what interviewers probe, and a walkthrough of one 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 common mistakes.

Use the guides 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. Their rules on using AI during interviews also differ widely. Learn your company's rules before the interview.

Anthropic

Anthropic pairs practical, implementation-heavy coding with an explicit values interview. That values interview rejects 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.

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

OpenAI

OpenAI publishes its own grading standard: well-designed solutions, high-quality code, performance, and test coverage. It may run system design twice in one loop. Product-flavored design questions expect full-stack answers: wireframes, API contracts, and schemas, not only a backend diagram.

xAI

xAI moves from first call to offer in two to three weeks. It requires a "Statement of Exceptional Work" with the application. Many loops end with a presentation of a project you owned. There is no dedicated behavioral round; interviewers probe ownership and autonomy inside the technical conversations.

• 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 relates to AI search: RAG (retrieval-augmented generation), retrieval, crawling freshness, and the tradeoff between cost, latency, and quality.

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

Mistral AI

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

Cohere

Cohere, the enterprise-first lab, tests production ML code. You write tests and run your solutions, and recited LeetCode answers get flagged. Unusually among AI labs, it 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

Hugging Face, the open-source ML company, hires like an open-source project. There is no LeetCode. Expect two to three conversations plus a take-home built on real problems the company is working on. You present and defend the take-home afterward. Your public GitHub and Hub activity work as a standing portfolio, and the cover letter genuinely matters.

AI sector at a glance:

Big Tech

The established giants run the most structured loops. Each grades culture against a named rubric (a written scoring guide). Microsoft scores growth mindset. Netflix applies the keeper test. Nvidia screens for calm responses to blunt criticism.

Apple

Apple's process is decentralized: each team designs its own loop. Behavioral evaluation happens in every round instead of one dedicated round. The consistent standard: 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. Inclusion is an explicit scoring dimension. Use STAR (Situation, Task, Action, Result), then add what you learned: the 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. The keeper test (managers ask whether they would work hard to keep each person) shapes every round. Study the memo like a syllabus, because it works like 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 come almost entirely from that team's actual work. Candidates commonly report waits of five weeks or more after the onsite. The behavioral screen reflects a famously blunt culture. The central probe is how you receive hard, public criticism.

• 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?"

Dev tools and enterprise at a glance:

Defense and Frontier Tech

The defense and hard-tech companies add checks that nothing else has. At Anduril and SpaceX, mission conviction is screened in every round, and mixed feelings are a detectable, disqualifying trait. At Waymo, the same seriousness applies to safety mindset and self-awareness.

Anduril

Anduril screens for genuine motivation to build defense technology from the first recruiter call. It asks pointed product questions, like "what is your least favorite Anduril product?" Technical questions are deliberately ambiguous, and how you extract clear requirements is graded. Most roles require US person status.

Defense and frontier tech at a glance:

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

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

1. Practical coding is replacing puzzle coding. Many companies now evaluate through realistic work: take-homes, pairing, debugging, code review, and build-a-feature rounds. Examples include Stripe, GitHub, Canva, Shopify, Ramp, Jane Street, xAI, DoorDash, Vercel, Discord, Intuit, ElevenLabs, and Hugging Face. Pure LeetCode preparation now covers a shrinking share of the market. Pattern fluency still matters everywhere, but shipping clean, tested code while explaining your steps matters more. Grokking the Coding Interview builds the pattern base that transfers across all of these formats.
2. Behavioral rubrics are increasingly published. More companies than ever tell you exactly what they score. Examples: Netflix's memo, the named values at Atlassian and Canva, ByteDance's ByteStyle, Databricks' principles, and Amazon-style calibration rounds at Oracle and Uber. Once you know that, the preparation is mechanical: map stories full of evidence to the named values. Grokking Modern Behavioral Interview covers the method.
3. System design is splitting 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: start with Grokking the System Design Interview, use Grokking System Design Fundamentals for the building blocks, and use Advanced System Design Interview, Volume II for depth. The final layer is company-specific, and that layer is what the guides above are for.
4. AI-use policies now define interviews. The range is wide. 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. Rippling makes tools optional but grades you against a different rubric depending on your choice. Always confirm your company's policy. If AI is allowed, practice a verify-everything workflow beforehand. For AI fluency itself, Grokking Modern AI Fundamentals covers the vocabulary that now appears in 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. Plan your pipeline deliberately: start the slow processes first, and expect the fast companies to demand decisions early.

FAQ

How long does a tech company interview process take? Anywhere from 11 days (Ramp) to 10 weeks (Google DeepMind). The industry median is 3 to 6 weeks. 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. Most big tech runs classic architecture rounds. Some run domain-specific design (Citadel's order books, Perplexity's RAG pipelines). Palantir asks you to break down vague problems. Jane Street and Ramp place design questions inside coding rounds.

How different are behavioral interviews really? Very different. 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. Shopify replaces the whole category with a life-story conversation. Read the company-specific guide before reusing your standard stories.

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

We update this guide as we publish new company guides. To build the fundamentals that transfer across every loop, explore our courses, starting with Grokking the Coding Interview and Grokking the System Design Interview.
