ZoomInfo interview questions

Had to complete a rapid-fire behavioral and IQ-style assessment. The platform they used would give you between 15 and 45 seconds to answer a brainteaser, then immediately go onto the next one. For my coding challenge, I had to answer 2 leetcode-style questions. The proctor for the challenge pushed me to do the challenge in a language of his choice (because it was one of several languages I included on my resume which I have experience with). I had been doing my leetcode prep in Python, so this very much threw me off guard. I was able to complete both problems in time but I wasn't selected to move forward, likely because I was struggling on syntax.

The recruiter sent a link to schedule an interview timeslot. I waited half an hour and the interviewer did not show up. I emailed asking if we should reschedule and the interviewer sent a confusing email where they explained they were busy due to high priority meetings and that we will re-connect later. I got a rejection letter instead. Bizarre and unprofessional experience- completely disrespectful of the time I took away from my own job to try and interview with the company.
