Went through 4.5 rounds of interviews (4 plus a mandatory presentation review with a manager) before getting rejected with NO FEEDBACK WHATSOEVER. I requested feedback and was told I'd be followed up with, but never was. And the cherry on top: the job was reposted, so I don't think they hired anyone. Utter disrespect for the candidate's time and feelings.

An outside recruiter had reached out to me to set up a first call. With the hiring manager. We connected and had a great conversation. Follow up calls were set up with a counterpart/peer on the team, and then an east coast manager. I was moved forward and asked to complete the take home exercise, which comprised of a customer email response, and a mock QBR deck. Once I returned the QBR deck, they immediately asked for revisions--before I had even presented. Extremely odd and something no other company has done before in my years of CS experience. I made adjustments and added in detail that was requested, only for the hiring manager to tell me that they're not going to have me present what I had prepped. Hours of research, prep and calls just to get the rug pulled out from underneath me. Extremely unprofessional and frustrating.
