Usual phone screen, multiple hiring manager meetings, cross-functional interviews, and final project. After the final interview and project review, there were an additional 2-3 interviews. One yellow flag I noticed was during the first interview when the hiring manager noted that several senior leaders left the company after just a few months because "they couldn't handle it here". Overall, I invested about 20 hours into the process. Not an insignificant amount for a role. After a week of silence, I received a generic rejection letter. Pro-tip for recruiters: If a candidate makes it to final rounds and has invested almost a half work week in the process, it's considered unprofessional not to deliver this news via a personal call or email explaining more than "we went with another candidate"
