I first had one on-campus interview with two engineers. They both asked easy questions but had a lot of interesting follow-up questions about runtime and modifications.

Bloomberg cares a lot about these optimizations because even small rounding errors or loss of precision could mean a lot of money in the financial market. I overlooked that the last time I applied for a summer internship, and that's probably why I was rejected then.

The second and final round was onsite. I had one interview with engineers, who were both super awkward, and I definitely thought I failed it. They asked random questions about treemaps, which I botched, but they were interested in my experience with scalability and distributed systems.

My next interview was with HR, who just asked me about my personal career goals.

My last interview was with a manager who was super chill. We mostly talked about my projects and goals, but then he asked me a brain-teaser-like question that I got mostly right.

To be honest, I'm surprised I got an offer. Maybe the two awkward interviewers liked me more than I thought?

Random question about treemaps that I got wrong... but apparently, I did okay enough to get an offer.
