DXC Technology Technical Writer interview questions

I was contacted by one of their recruiters through LinkedIn. He asked if I would be interested in speaking to him about the role but obviously pasted the wrong job description in the message. That was red flag number 1. We schedule a phone interview and when the day arrived, I was called by his coworker to tell me he wasn't with the company anymore, so I would have to reschedule. When the date of the next interview attempt came, I was left hanging for an hour and then told through email that my new interviewer had lost her voice so we would have to reschedule. I followed up with some emails but then I never heard back for about 3 weeks. One day, I get another call from that same recruiter saying that she didn't forget about me and would call me tomorrow at at 5:30 p.m. Yet again, I waited for an hour and AGAIN got stood up. Incredible. To add insult to injury, she did end up calling me that day...almost at 9 p.m. and while I was in a crowded mall without a single support material or even a chair. She still insisted to do it, and it went as well as it could have been expected. If this is how this company operates, I think I might have dodged a bullet (but lost a lot of time).
