I was informed 1 hour before my interview was scheduled to begin (at 9am) that it was cancelled, via email cancellation event. This was at 8am while I was on my way to the interview, the reason being an offer was sent out to another candidate the night before.
This is highly unprofessional and unacceptable! That is not how you manage an interview process or treat potential employees!
I would advise to approach this company with extreme caution!
