4 interviews starting with people I would work with on a daily basis, then their manager, then his manager, then the CEO of the company. Overall it was a negative experience because after 4 interviews, nobody from the HR department or my hiring manager ever called or wrote me back. Final hour long interview with the CEO was the last I ever heard from this company. My “thank you for allowing me to interview” emails went unreturned, my “any update on the position” email went unreturned.
