I was scheduled for their Interview Blitz day for two interviews that were supposed to happen back to back. Neither of my interviewers showed up. A week later I got them rescheduled, but they left me in the dark for a while before rescheduling.

I was referred for the role by an IBM employee. Rather than a screening call, I was randomly sent an invite for an AI interview asking behavioural questions. A week later I was sent an email by IBM HR (in Taiwan) asking me about my residency status and expected salary, then scheduling an interview with the hiring manager (or so I was told). Was not given any indication of what the agenda of the interview was, and HR wasn't forthcoming either. As it turns out, the interview was with two members of the team rather than the hiring manager. The questions being asked also led me to conclude that they were after someone from a technical sales background which was not aligned with my experience or the role as it was described. Anyway was told I would hear back from them a week after with next steps, but two weeks later, nothing was forthcoming. Ghosted basically. Only after multiple polite emails to HR was I finally sent a generic rejection saying they were moving ahead with other candidates. Lo and behold, a week later the role was readvertised.
