Practise Google interview questions.
Free practice for Google software engineer, PM, and TPM interviews. 1000+ MCQs, AI-graded estimation questions of the kind used in PM and system-design rounds, and written preparation guides to the Google loop.
What the Google loop actually looks like.
Google's interview loop is famously structured: a coding screen, two or three coding rounds at on-site (DSA-heavy), at least one system design round at L5+, and a Googleyness/leadership round. PMs face product-sense, execution, and estimation questions; TPMs face a hybrid of coding, design, and project judgment.
Coding screens
DSA-focused. Two-pointer, BFS/DFS, dynamic programming, backtracking. Strong emphasis on edge cases and complexity analysis.
System design (L5+)
Design at scale. Capacity planning is part of the rubric, so expect to do back-of-the-envelope math on QPS, storage, and bandwidth.
Estimation / guesstimate (PM, occasionally SWE)
Market sizing or capacity estimation. "How much storage to host all Google Street View images?" is a real example. Structure beats final number.
Behavioral / Googleyness
STAR-format examples of leadership, ambiguity, and disagreement-and-commit.
Topics Google interviewers lean on.
Practise the languages Google screens on
What separates offers from rejections at Google.
- 1
Talk through the problem before coding. Google interviewers grade communication explicitly.
- 2
For system design, do the back-of-envelope math early. Don't skip to architecture.
- 3
Expect at least one estimation question. Practise structuring assumptions, not memorising numbers.
- 4
On coding rounds, write tests as you go. Walking through a few cases earns you signal points.
Train the muscle, not the answer.
Thousands of free MCQs, AI-graded guesstimate practice, and an AI tutor. Every practice question and its grading rubric is free to read before you start. AI grading is capped at 1 answer a day on the free plan and 30 a day on Pro.
