Long, but well worth the time commitment. By the end, you should have had 3+ calls with your future manager, which, in my opinion, is really nice. So much of your happiness and success at work is based on your manager.

Process was:

1. Recruiter call
2. Hiring manager behavioral screen
3. Technical screen with future team members
4. Take-home code assessment
5. Executive 1-on-1
6. Hiring manager pt. 2 + walkthrough for presentation
7. Presentation
8. Optional: additional 1-on-1s with team members or cross-functional team to assess what level you should come in at.
