Free tool · no sign-up · 5 interview rounds
Generate AI-powered Google interview questions for all 5 rounds. Process: Phone Screen → DSA × 4 → System Design → Behavioral.
From our curated bank of 10 Google-specific questions. The generator produces fresh AI-tailored questions each run.
What is the typical Google interview process and how many rounds should you expect?
Tip: Google India: recruiter screen → 1 phone interview → 4–5 onsite rounds (DSA × 3, system design × 1, behavioral/Googleyness × 1). Total timeline: 4–8 weeks. Each interviewer submits independent feedback — any strong no-hire can block an offer.
How would you find the kth largest element in an unsorted array efficiently?
Tip: Optimal: QuickSelect algorithm, O(n) average time (Lomuto partition). Alternative: min-heap of size k, O(n log k). Sorting is O(n log n) — too slow for large n. Google DSA rounds test both the approach and your ability to discuss trade-offs.
Design a URL shortener system like bit.ly.
Tip: Core components: base-62 encoding of an auto-increment ID, read-heavy KV store (Redis), redirect via 301/302. Scale: ~100M URLs → distribute across shards. Handle: custom aliases, expiry, analytics counters. Google system design rounds test depth — discuss CAP theorem tradeoffs.
Given a binary tree, write code to find the lowest common ancestor of two nodes.
Tip: Recursive: if root is null or equals p or q, return root. Recurse left and right. If both return non-null, root is LCA. If only one returns non-null, that is LCA. Time O(n), space O(h). Google favors clean recursive solutions with edge case handling.
What is Googleyness and how do you demonstrate it in an interview?
Tip: Googleyness: comfort with ambiguity, genuine curiosity, collaborative spirit, and intrinsic motivation to have impact. Don't rehearse Googleyness — interviewers detect performance. Real examples of working through an open-ended problem or failing fast and iterating are what land offers.
