I had an initial phone interview on HackerRank with an engineer at Bloomberg.

Then, I was called to have a 2:1 interview with junior engineers, on-site.

After that, I was called back for a final on-site interview with a Senior Engineer and an HR representative.

The first two rounds focused on algorithms and data structure questions, while the final round was more of a systems development question.

I was rejected at the final stage due to a conflict of interests and goals.

The recruiter was very friendly and helpful, and they even provided feedback.

Very similar to questions on HackerRank and LeetCode. Also includes a few HR questions.
