Invited directly to on-site in Mountain View due to strong referral. Interviews were extremely hard questions, over my experience and knowledge. Interviewers seemed quite boring individuals to work with. Questions can range from system design to sorting algorithms.

Very standard Google interview. First round recruiter to outline and chat, 3 rounds of technicals, then a final hiring committee round. Unfortunately I didn't make it past the last round, and be wary there is a 1-year cooldown period before you can attempt again. The technical rounds themselves weren't particularly hard if you are competent.

I applied through website. They gave a phone screen then a coding test And I have to discuss the problem and my solution orally The problems look like leet code So you have to brush up data structures and Algorithms
