1. Online Assessment proctored through CodeSignal. I received a score mid 400's / 600. 4 questions LeetCode style, I was able to complete first two within 10 minutes, 4th I completed half way, and 3rd about 2%.
2. After OA results were verified by CodeSignal, was called back within 2 business days from the recruiter saying I passed and was moving on to the Power Day interviews.
3. I received a prep packet about 5 days prior the Power Day which included links to GeeksAndGeeks top 10 interview problems, tips and resources for STAR behavioral interviewing, and a few resources on the Case interview.
4. I also received my Power Day interview schedule: 2 technical 1 hour interviews, 30 minute break, the 1 hour behavioral, and 1 hour case study.
4. Power Day arrived, The first two technical interviews took the full hour (left 5m for questions). Behavioral and Case had plenty of time for questions at the end.
Every interviewer was extremely polite, and given my first interview ran right up to time, the second interviewer gave me a couple minute break before beginning.
I say average difficulty because technical aspects were not too difficult (not even LeetCode style - more word-based, real-world problem solving. Behavioral is typical STAR, which I find somewhat difficult).
