I had a standard phone screen and then moved on to the final round onsite.

The recruiter asked for my availability to discuss the rest of the process. I sent it in, and she didn't respond until much later, when she tried to contact me during one of those times.

This was totally unprofessional. If I extend the courtesy of sending my schedule in advance, I shouldn't have to put all those times on hold because you can't give a two-second response.

She did the same thing again a week later, and I ended up withdrawing from the process.
