GoGuardian Senior Software Engineer interview questions

They approached me for this position and scheduled a technical interview. The first time, it was cancelled at the last minute and rescheduled for the next day. For the second scheduled interview, I joined the call on time, but no one showed up. I reached out to HR, but there was no immediate response. After about half an hour, she replied saying there had been a production issue and the interview was cancelled, though I was not informed beforehand. She mentioned it would be rescheduled, but I never heard back again. Overall, the experience felt quite unprofessional.
