Verbal offer rescinded due to a secondhand reference

really feeling down in the dumps right now… I crushed all of the interviews and went into the weekend with confirmation that an offer is being put together for me. It’s now Wednesday and I just received news that they no longer want to proceed with me because one of the interviewers knew someone that knew someone senior that overlapped with me and said that I’m incapable of leading a team and needs oversight.

I’m 7 years into my career and this is a VP level role. I’m stunned and honestly questioning my entire career and network now. It’s hard not to let this get to me…
