Five groups of engineers interviewed me in turn, which took about five hours. Questions included fundamentals of algorithms and numerical analysis tricks. It was a very interactive and friendly atmosphere, and the questions were interesting to solve.

The interview process consisted of one telephone interview and three independent video interviews. I performed poorly when answering several challenging questions from the last interviewee, and I eventually missed the opportunity.

The interview process included two phone interviews and an onsite interview. The problems were well explained, and I had opportunities to ask questions. The interviewers were nice. I had to decline the offer due to family issues.
