The total process took 5 months. The longest and most painful ever in my career. Here's the break-down:
First step: 30 min phone interview with a recruiter
3 weeks later: 1 hour in-person interview with hiring manager (including portfolio presentation). Design exercise was provided.
2 weeks later: 30 min phone presention of design exercise proposal to hiring manager and one team member
5 weeks later: 30 min in-person meeting with hiring manager
3 weeks later: 1 hour in-person interview with two team members
2 weeks later: 4 hour in-person interviews/presentation with hiring manager and same three team members I had met with before, plus lunch with hiring manager
2 weeks later: negative decision was communicated via recruiter that they decided to pass because I wasn't a cultural fit.
