The interviewer directly jumped into code questions without many questions about my background. First one is a easy leetcode question, second one is a medium leetcode questions. Each session is 45 minutes.

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.
