The interview was very rushed, and the interviewer generally wasn't listening to me.

For one problem, I proposed two possible ways of approaching it (let's call them A and B). I explained that method A would be the better approach and was starting to implement it, but he asked me to implement method B instead. I made sure to point out method B's cons as I was coding to show that I understood the code.

After I was done, he started explaining why B wasn't a good method and seemed unimpressed. However, he was the one who made me stop doing method A and do method B in the first place. At this point, it confirmed my suspicions that he had only been half-listening the entire time.

Additionally, from what I saw, I was surprised by how dated some of their systems appeared to be.

The recruiter emails were super disorganized and in a literal typewriter font.

Overall, it was a very odd interview experience and not what I was expecting from a company as large as Bloomberg.
