Labcorp Research Assistant interview questions

Initially a phone interview with recruiter about 20 mins to hear more about the position and what I was looking for. Was contacted initially by phone and email from a senior recruiter set up appt to discuss job and what I was looking for in a position their.

I only got through the phone screen and was scheduled for an onsite interview until they cancelled on me. The phone screen was simple and to make sure I was still interested. HR then contacted me again saying that they wanted an onsite interview and to list three dates and times that work for me. I sent them an email back on what times and dates worked for me. I heard nothing back, so I decided to email again to make sure they got my email. They emailed me back saying sorry and to give them three more times and dates. I do and again, I hear nothing from them. I sent them emails for the next two weeks asking if I'm still being interviewed. It wasn't until the second week after all the chaos that I was told that the management changed their minds and they weren't hiring anyone. It was a complete waste of time.
