I had two phone interviews before I got rejected - the first of which was a brief chat with their HR team to learn more about the opportunity, the second of which was with one of their operations manager and was more specific to the applied position.
It was extremely poorly organised between the first and second interviews. The interviewer for my second one did not call me as scheduled (and didn't give any notice regarding his absence in advance) and it took 1.5 months and four emails from my end to reschedule another one. It also turned out the HR who was responsible for the rescheduling left the company in between, but there was no one else from the company to follow up on my application.
When the (same) interviewer finally called me, he was 15 minutes late, and while I understand the occurrence of any unexpected events/last-minute emergencies, I would have expected some sort of apology for the delay (for both the call and for the time it took to reschedule). The interviewer didn't bother to introduce himself, was very uninspiring and didn't sound like he was passionate about his current job, nor did he sound interested in speaking to me at all. There was a lot of background noise from his end and I found it very distracting. Even when I asked the interviewer several questions at the end of the interview, I didn't feel like I learned anything more about the company and about the role than I already knew.
It was one of the most negative interviews that I've had and incredibly unprofessional - a huge shame because the company sounds so innovative with its rapid growth and product launches, which unfortunately was not translated at all during the interaction I had with them.
