Bloomberg Software Engineer(Internship) interview questions

Got invited on interview online, but no one showed up. After messaging HR they scheduled another interview. This time someone came but was unpleasent. After this talk I resigned, if this is how interviewers are like, Im worried about rest of the company.

1. Leetcode easy (1 interviewer), 2. leetcode medium/easy (2 interviewer), 3. System Design, 4. HR, 5. EM Manager. Still waiting for decision after one week. Quick responses for the first 4 rounds (1-2 weekdays).
