Question Bank FAQs
What is the InterviewLift Question Bank?+
A 48,000+ company-specific interview-question database indexed by company, team, level, and round type.
Which companies are covered in the question bank?+
Google (4,800), Amazon (5,200), Meta (4,100), Microsoft (3,700), Apple (2,300), Netflix (1,100), plus deep coverage of Stripe, OpenAI, Anthropic, Databricks, Snowflake, Uber, Airbnb, LinkedIn, Salesforce, Atlassian, and 200+ other companies.
Where do the questions come from?+
Our team compiles the questions by company, role and round, from what candidates and our success managers report from real interview loops. Treat them as practice material: no list can promise the exact questions you'll be asked.
How is the question bank organised?+
By company → team/org → role → level → round-type. So you can filter to e.g. "Google → Cloud → SWE → L5 → System Design" and get the exact subset of questions Google L5 system-design interviewers asked at Google Cloud in the last 24 months.
Do you include behavioural and system-design questions?+
Yes — all four major round types are covered: coding (LeetCode-style + product-coding), system design (with rubric phrasing per company), behavioural (mapped to each company's LP/values), and role-specific (e.g. SQL for data roles, ML system design for ML roles).
Is there a free trial?+
InterviewLift is free to install, and every new account gets 15 free questions with Jarvis, no card needed. To try a full live interview, the 1-round Jarvis pack is the way in. Gold and Diamond plans come with a 3-day money-back guarantee.
