I took the phone interview at FB, which included two Leetcode problems (easy/medium) level, with big(O) follow up. No resume went through or other stuff, only the algorithm problems were asked. Overall it felt good, the interviewer gave hints when I stuck.
I applied online. The process took 2 months. I interviewed at Meta
Interview
7 Interviews, didn't receive an offer after the final round. Time-consuming process, which includes multiple rounds of technical interviews (design, coding, behavior, etc.) and a 1-hour research talk. The team leader was unpleasant to interact with.
recruiter call, technical interview, research interview, and job talk (presentation), hiring manager interview, everything was organized in the website so it was easy to navigate through the process, and recruiter was always responding super quickly
