Bloomberg Software Engineer Internship interview questions

One phone interview with a simple base conversion problem, then invited for an on-site in the London offices. There were two interviews, one technical and one with a senior engineer and HR; the first interview consisted of three simple algorithmic problems, whereas the second one involved switching back and forth HR questions with a systems design one. The systems design question was not hard either. The last interview ended soon after discussing my academic plans for the future.

First did a technical phone interview, for which the interviewer was 15 minutes late. A week later was contacted about an onsite which I had moved up to the same week due to other deadlines. Had two technical interviews, with two engineers in each. Overall they seemed really low energy and not enthusiastic about their jobs/work at all. Was given a measly lunch in between interviews but not enough time to finish it, also we were expected to just eat alone in the interview room. After the techicals they said they wanted two more interviews, one with HR and one with a senior engineer. HR just asked standard behavioral stuff, and 'why bloomberg.' Senior engineer was over video call but just standard resume stuff. At the end he asked if there was anything that would stop me from acceping an offer. Afterwards was immediately asked to leave with no tour given even though they had said one would be given.
