Bloomberg wants you to prepare for the technical interview as if you were interviewing for FAANG. I interviewed for both FAANG and Bloomberg, and I can assure you there is a big difference in terms of approach.

In my case, they started with a fairly standard algorithmic question, LeetCode easy, then built on that. They essentially probe and try to find a weakness. It's not about solving the problem; it's about solving the problem in the way they want you to solve it (for instance, don't do it recursively; do it iteratively).

There were a lot of open-ended questions and behavioral questions thrown into the mix. Possibly, every interview is different.

Regardless, there was no feedback, just an automated email notifying you that you failed. The decision for the technical interview takes into account behavioral factors. If they don't like you for whatever reason, they will fail you.

After all, I solved around 90% of the 10 iterations of the problem I was given, and they still failed me.

A fairly simple recursive mathematical function.
