Avanade Tester interview questions

I passed the first interview. It was online and went great. Second interview was very hard to arrange as they would not send me a time they were free so I sent them my schedule which apparently they couldn’t fit in either so after 2 weeks they finally sent me a schedule to interview. I picked a time and confirmed on my end half a week before the actual time. They didn’t confirm back, and the HR lady was very confused when I asked for the confirmation email the day before; apparently the interview wasn’t confirmed, so I wasted my time. Then they didn’t reschedule a second interview and I got ghosted
