Got an email from the hiring manager a couple of days after applying requesting a 30 minute screening interview. He called me on the date/time we agreed on and told me he forgot to send me Teams meeting ink and rescheduled the meeting. Without any explanation he changed the interview duration to 1 hour in the updated meeting request. I logged into Teams meeting on the rescheduled date/time and he did not show up. I sent him an email telling him I waited for 15 minutes and wanted to know whether he still wanted to interview me. He replied a couple of hours later telling me to reschedule. We had an interview the next day, and never heard from him again. I even followed-up later but no response. That is the level of professionalism shown by this company.
