Live technical mock interviews with FAANG+ engineers
Prepare for your next technical interview with a live system design mock interview or coding mock interview led by experienced FAANG+ engineers. Practice realistic interview questions, receive detailed feedback, and learn exactly how to improve your architecture, problem-solving, communication, and trade-off analysis before the real interview.
Choose your mock interview type
Whether your next round is an algorithm screen, backend design round, senior system design loop, or target-company onsite, our mock interviews help you practice under realistic conditions.
Practice open-ended architecture questions with a senior engineer. Learn how to clarify requirements, design APIs, model data, handle scale, and explain trade-offs clearly.
Practice live coding questions with a FAANG+ interviewer. Improve problem-solving, communication, edge-case handling, code quality, and time and space complexity analysis.
Preparing for Google, Meta, Amazon, Microsoft, or another top company? Book a target-company session to practice the format, expectations, and evaluation style that best matches your real loop.
How it works
Every session is designed to feel like a real technical interview, followed by direct feedback you can act on immediately.
Choose a system design mock interview, coding mock interview, or target-company session. Pick the level and interviewer background that best matches your upcoming interview.
Work through a realistic FAANG-style interview prompt in a live 60-minute virtual session. Explain your thinking, ask clarifying questions, and solve the problem under interview-like conditions.
In the debrief, your interviewer identifies strengths, blind spots, and the most important next steps. You leave with a clear plan for improving before the real interview.
A system design mock interview helps you practice open-ended architecture questions in a realistic FAANG-style interview setting. You will work through requirements, APIs, data models, scalability, reliability, trade-offs, and bottlenecks with an experienced interviewer from a top tech company.
You will be given a realistic system design prompt, such as designing a URL shortener, news feed, ride-sharing service, notification system, payment system, or distributed cache. Your interviewer will evaluate how you clarify requirements, define APIs, choose storage, handle scale, and communicate trade-offs.
A coding mock interview helps you practice data structures, algorithms, problem-solving, and communication in a realistic technical interview. You will solve a live coding question, explain your approach, handle edge cases, analyze time and space complexity, and receive actionable feedback.
You will solve a realistic coding interview question while explaining your thought process. Your interviewer will evaluate your problem-solving approach, code correctness, edge-case coverage, complexity analysis, debugging, and communication.
Coding mock interviews can usually be conducted in common interview languages, including Python, Java, JavaScript, C++, Go, and other mainstream languages depending on interviewer availability.
After the interview
The value of a mock interview is not only the practice. It is the direct, specific feedback that tells you what to fix next.
Understand where you performed well and where you lost signal during the mock interview.
Identify gaps in architecture, algorithms, communication, edge cases, or interview pacing.
Leave with specific topics, drills, and resources to review before your real technical interview.

FAQ
Answers to common questions about booking, interview format, feedback, and choosing between system design and coding practice.
A system design mock interview is a live practice interview where you design a scalable software system, explain requirements, APIs, data models, architecture, trade-offs, and bottlenecks, then receive detailed feedback from an experienced interviewer.
A coding mock interview is a live technical interview practice session focused on data structures, algorithms, problem solving, edge cases, time and space complexity, and communication. You solve a realistic coding problem and receive feedback on both your code and your interview performance.
If your next round is system design, start with a system design mock interview. If your next round is a coding screen or onsite coding round, start with a coding mock interview. If you are preparing for a full onsite loop, booking both gives you broader coverage.
Yes. The sessions are designed to simulate realistic technical interview expectations from top technology companies. Target-company mock interviews can further align the practice session with the company and level you are preparing for.
Commonly supported languages include Python, Java, JavaScript, C++, Go, and other mainstream interview languages depending on interviewer availability. Choose the language you plan to use in your real coding interview.
You receive a verbal debrief and a prioritized list of fixes, topics, and drills to focus on. The goal is to make your next practice steps clear and specific.
Target-company sessions are designed for candidates who want interview practice calibrated to a specific company. Availability depends on interviewer background and scheduling.
Most mock interviews are 60 minutes, including the live practice portion and a feedback debrief. The exact breakdown can vary by interview type and interviewer.
Yes. System design mock interviews are especially useful for senior, staff, backend, infrastructure, and platform candidates because they focus on architecture depth, trade-offs, and communication. Coding mock interviews are also useful for senior candidates who need to sharpen algorithm performance before onsite rounds.
Yes. Many candidates book multiple sessions across coding, system design, and behavioral rounds to simulate a full interview loop and track improvement over time.
Book a live system design mock interview or coding mock interview with a FAANG+ engineer and walk into your next technical interview with a clear improvement plan.
