I’ve now gone through this process twice, and both times the hiring manager was beyond unprofessional. My first interview in May was over the phone, and the hiring manager gave a date on which I was told I was guaranteed to hear back either way. After that date had passed, and after a thank you letter and two follow ups, I took the hint and stopped reaching out. This November, I was offered an interview for the same position and was sent a link to select a time slot. Despite selecting a time slot offered, the same hiring manager changed my interview time without consulting whether I was still available, and wrote to say that he’d changed my slot and he “[hoped] that [worked] for [me].” I reached out to confirm that I was unavailable for that interview and provided three days of availability; he didn’t respond, and called me during the time slot that he’d selected for a rescheduling. I immediately emailed to confirm that I was unavailable and reiterate my updated availability and he didn’t respond. It took another follow up and a note through the hiring service, as I wasn’t sure he was receiving my emails. After those four follow-ups, I still didn’t receive a response. Today, a week and a half after our scheduled interview, he informed me that the position was filled (in response to my three emails regarding availability which, evidently, had been received). Twice now, I’ve wasted my time trying to communicate with this individual, and I will not make the mistake of applying to work on his team again.
