2 OA 2 phone interview - medium to difficult LC coding (original question should be medium but may have follow up) Onsite - 4 round, I feel like interviewers are from different groups, so content varies, some are focus on my past experience, some are forcus on coding and CS fundamental knowledge My interview process was pretty good, interviewer are nice, and may offer some hints when I got stuck. And HR was very responsive.

Good experience, the interviewer is friendly, would give reasonable hints. Though the coding problems are hard, one can still figure it out with the leading of interviewers. The interviews are also energetic, talking with them is an exciting experience.
