Went through 4 rounds of interviews over the span of a month. All of them seemed to go well and I was told during the last one they would be in touch. 2 weeks later, nothing, I sent a follow up email and still haven’t heard anything, not even a rejection email. I get it, but it’s simple courtesy after four rounds of interviews (!!!) to at least send a rejection notice. It’s incredible rude and unprofessional to ghost candidates.
