ZoomInfo interview questions

I received an email from HR that they wanted to interview and to choose a time on Google Calendar that was available for an interview. I did and received a confirmation that I would get a call on Monday at 11:30 am. Monday came around and the HR employer NEVER CALLED ME! I waited 30 minutes and gave her a call back, since she left her phone number on her original invitation email. I also sent her an email to follow up to see if she needed to reschedule. She never called me back or emailed me. Very bad business!

Had a phone screening that went well. Very nice and respectful company tech recruiter. Then a phone interview with the manager. Lastly I had an on-site with four engineers and the manager. very kind, and respectful team. great process and super chill. still waiting on an offer
