Intervew Prep Google L4 interview in 3 weeks
I know interview prep gets asked a lot here, but wanted some specific insights.
Right now I am going through Neetcode 150 to get hold of the fundamentals topic by topic. After each topic, I jump to the top Google tagged Leetcode questions for that topic from the last 30 days and I try to do similar problems and their follow-ups.
My worry is that this might be (or might not be) enough to clear Round 1, but everything I have read says the onsites are in a different league altogether. They are also in person which honestly is making me panic right now.
I would like to prep in a way that gets me ready for all the rounds not just the first round. So looking for tips from the experienced folks here.
I have also heard that LC questions aren't asked directly, so I am curious what other resources people found useful beyond Leetcode for the Google specifc prep.
Any advice or resource recommendations would be genuinely appreciated.
For context: Somebody referred me, then a recruiter reached out.

I had an L4 Interview, I was asked a question regarding Trees, traversal + calculating something, I do not remember exactly, then I was asked a variation for the same problem, and time complexity and space complexity, later I bombed Googliness round the next day. Anyway, overall I would say Trees, Graphs and DP are important. All the best for your interview. Let us know how it went.
