Bloomberg Software Engineering Intern interview questions

I applied through an on-campus virtual conference, after a 10-minute talk with an engineer about my experience there were 2 technical rounds with engineers (all virtual). The whole process took less than a month. Weird disparity in interviewers though, my first interview the guy was very collaborative, encouraging, engaging, etc., didn't really seem to mind if I didn't remember something. The second interview I had two people who weren't really responsive, felt more like a 'normal' technical interview where they're just there to judge whether or not you get the problem, didn't talk much except to give hints. Not sure if this was intentional on Bloomberg's side

1 phone interview, then 3 on-campus interviews: 2 technical + 1 HR/behavioral. Was asked questions about both software design and algorithms, mix of medium and easy questions, but the interviewers were helpful on the harder questions.
