Conducted interviews and problem-solving sessions with four individuals. The problems ranged from basic to intermediate in difficulty. Ample time was given to solve each problem, approximately one hour per problem. A complimentary lunch was provided.

Co-operative interviewers. Be honest about what you know and what you don't. The interviewers will steer the interview towards what you know. I had 4 rounds, but mostly they have 3 only.

The process involves multiple stages. The last stage included a full loop with multiple interviewers. The questions seemed reasonable. If you perform well but are not considered a diverse candidate, be prepared for a potential multi-month wait time
