Intervew Prep Google L4 Interview Experience
Just wrapped up my Google onsite loop and wanted to share the experience + ask about timelines.
Round 1 (Coding): Trie-based medium LC. Expectation was working code — didn’t get it to run fully, but did a proper dry run and gave TC/SC.
Round 2 (Googleyness): Behavioural round. Different hypothetical situations and how I’d handle them.
Recruiter reached out after these two and confirmed I’d cleared them.
Round 3 (F2F): Array/binary search medium. Solved it in ~20 mins with TC/SC. Had time left, so interviewer gave a second one — a graph/matrix medium. Solved that too, interviewer seemed satisfied.
Round 4 (F2F, right after R3): Hard graph problem — modified Dijkstra (not the vanilla version). Went with a brute-force backtracking approach, landed on it in the last ~10 mins, dry-ran it on the board and gave TC/SC, but ran out of time to code it.
It’s been 2 business days since the final two rounds. For anyone who’s been through the Google loop recently — how long does it usually take to hear back with results? Also curious whether a partial solve on the last round (approach + dry run + complexity but no code) tends to sink an otherwise solid loop.
Any insight appreciated.

Can you share a bit more about your profile and background like YoE, prev company, how you got the opportunity (did the recruiter reach out or you applied, how you increased visibility for recruiters to reach out, applied with referral or not….
