A month after I applied, I was invited to do a phone screening with the hiring manager and 3 other people I'd be working with. They asked pretty straightforward questions about why I wanted to work at Columbia and about my experience. About a week later, they called to let me know that I was invited to do the in-person interview on campus. The in-person interview was a whole-day event and I was scheduled to meet with a total of 20 people (not individually; I met with groups of 2-5 people). It was really informal and everyone was really friendly. The process went bad after the in-person interview. The hiring manager said he would give me a decision by the end of October. That deadline passed and about a week into November, I followed up with the hiring manager via email to get a sense of his updated timeline. Got no response. It's been a month since my interview and it looks like I'm no longer being considered. I hate it when employers don't have the courtesy to inform candidates (specifically candidates who had in-person interviews) that they're no longer being considered. So annoying.
