Hmm on one hand I am sympathetic to someone that may have had a rough day, and things happen, but on the other I expect a high level of quality in the people around me like you said and I am in a place in my life where I don’t need the extra money or need a new job, I am still working for my current company. The way I see it, If you’re a manager and need to be told to apologize to someone after you blew off the interview with them, I don’t know if that’s redeemable. While I appreciate the gesture of the apology, this clearly didn’t come as a sincere apology given that I told the recruiter this is a reason for backing out.
