Egress interview questions

Contacted by internal recruiter, interviewed online, then another interview with head of BDR team, they were both very friendly and gave a great impression. Was invited to a final stage interview with the CRO, turned out to be a massive waste of my time as the interview was ended abruptly by a small detail that, if it mattered to them, should have been mentioned in the first interview. This detail had been discussed in the earlier interviews and at no point did anyone lower down the management structure raise issue with it, then the CRO said it was a dealbreaker when he found out. Ended up wasting two weeks of both of our time.
