Very tranditional google interview process R1+R2, 3 LC hard with follow-up and 1 bq. Didn’t pass for not thinking of optimal solution by myself in the last round. Interviewer was not helpful

The process was technically rigorous, involving five back-to-back rounds focused on algorithmic efficiency ($O(n)$ optimization) and system trade-offs. While the engineers were brilliant and the problems intellectually stimulating, the post-interview stage was slow. A 5-week communication gap, complicated by international holidays and immigration reviews, created significant timeline uncertainty.
