Was contacted via LinkedIn by a recruiter for a manager position at AWS. Did two phone screens with recruiting team, 1 phone interview with hiring manager, 1 phone interview with hiring manager's manager, was contacted by recruiter saying the position I interviewed for was filled but another was open and they saw a fit. Had a prep session with the recruiter for in-person interviews. Completed a writing test which was answering yet another interview question. Flew to Seattle for about 8 hours of interviews (most 1:1), but final hour was panel of 3. Most interviewers requested that I do not send a thank you email. Sent thank you notes to those who didn't ask me not to send one. Never heard back from recruiters, HR, or anyone following all of that. Never got my parking, food expenses reimbursed. It was a grueling process. Most of the team was very pleasant. I was impressed with the energy that goes into interviewing candidates and the way they prep you. I was unimpressed that after the time and resources both they and I invested in the process no one followed up. I reached out afterwards, but never got any reply.
