I got a phone interview a month after applying to Bloomberg's 2022 New Grad position.

The Phone Screen started with asking me a few behavioral questions, such as tell me about yourself and tell me about a project you worked on.

Then, we proceeded to the Hackerrank page where he described a problem and asked me for a solution.
I came up with an optimal solution very quickly. However, he didn't seem very happy and spent 10 minutes trying to find a flaw and every test case possible. Finally he gave up but he did not seem satisfied with my code.
**The problem was checking a string without spaces for specific words within a dictionary. I basically reverse looped it and used a temporal string to check for words that match.

After that there were like 15 minutes left and he jumped onto giving me a second problem. I blanked out and wasn't able to come up with the trick to it. But I think I came close with a brute force solution and some pseudo code. He ended the interview then and asked if I have any questions for him.
**The problem was finding the maximum product of 3 elements within a List that contains negative and positive numbers. *Yeah easy I know :(

Overall it was quite a bad experience. The interviewer was very quiet and unhelpful. I received 0 hints and every one of my ideas was criticized. I've read that usually BB interviewers are very helpful and easy going so I guess I just got unlucky that day.
