The interview process was chaotic; I was handed off across multiple recruiters over the course of just a couple of months.

Initially, I was told I would need to go through a phone screen, then that I wouldn't be. Ultimately, I did not participate in a phone screen and went directly to a virtual version of the on-site interview.

The on-site questions felt better than I expected, and I thought that I answered most of them well. I had forgotten about one particular data structure and had to use some features of my programming language that I hadn't prepared for. I noted this and continued with pseudocode.

Upon receiving word on my hiring decision, my last recruiter emailed me an upbeat email asking to schedule a time to talk. This doesn't set up good expectations. According to my friends who do recruiting, this shouldn't be done for a rejection call.

They were able to give feedback, but I thought their reasons for rejection were bad. I would have preferred no feedback to that.

If you're not desperate for a job or even a little rusty on your undergraduate work, I do not recommend taking the time to interview with Google.
