I was being interviewed by Alpha Inc. while still employed by BetaCorp. Alpha Inc's interview process took several weeks and, between the second and third interview, BetaCorp and I parted ways.
When should I have told Alpha Inc. that I had left BetaCorp? While several trusted friends pointed out that I didn't have to let Alpha Inc know about my employment situation change, I suspect part of Alpha Inc's hesitation in moving faster with me was due to their belief that I was still actively with BetaCorp. I also felt weird about not letting them know sooner. It felt ethically gray, so I'm curious what pro recruiters / hiring managers would say they prefer. I definitely want to know for next time, should I find myself in the same relative situation.
