Waystar Manager, Security Operations interview questions

After being ghosted prior (red flag 1) I got an email to discuss a position other than that one I applied for (red flag 2). I went along with it and was scheduled for an interview and accommodated the interviewers schedule (Director). Waited for approximately 15-minutes on the Zoom interview, the interviewer was a no show. I sent an email expressing my frustration and withdrawal based on the second show of unprofessionalism.. The interviewer, in response, lied and said he was present when that clearly wasn't the case. Highly unprofessional, I suggest moving with extreme caution and too keep receipts as I did, they will try to repaint the scenery... If they can behave this way during the interview process imagine what employment with them could possibly be like. Negative experience but enlightening none the less.
