I applied through an on-campus virtual conference. After a 10-minute talk with an engineer about my experience, there were two technical rounds with engineers (all virtual).

The whole process took less than a month.

There was a weird disparity in interviewers, though. My first interview, the engineer was very collaborative, encouraging, and engaging. He didn't seem to mind if I didn't remember something.

The second interview, I had two people who weren't really responsive. It felt more like a 'normal' technical interview where they're just there to judge whether or not you get the problem, and they didn't talk much except to give hints.

I'm not sure if this was intentional on Bloomberg's side.
