I just did a phone interview with Bloomberg and wanted to share my experience as I got lots of help from here.
I applied through Bloomberg career site and got a phone interview scheduled today. Overall, it was terriable even though the interviewer seemed nice. Firstly, I was waiting on the phone call but no one called. After 15 min passed by, I got an email saying that I didn't answer the call so they asked me to reschedule the interview. I immediatly replied with my phone number(which I included when I scheduled this interview) asking them to do the interview today as I took the day off at work for this interview. After 5 min, I got a phone call from the interviewer.

It started out as any other interviews. He asked me what was the most proud project that I've done and we talked about it for about 10 -15 min. Then we went straight into the coding through hackerrank. Long story short, he gave me the wrong example which made no sense to me. I spent most of the time asking about the examples he gave me which I could not understand till the interview was over. After the interview was over, I looked up in the leetcode and realized that he gave me the wrong example.

Below is the problem he asked me.
662. Maximum Width of Binary Tree - https://leetcode.com/problems/maximum-width-of-binary-tree/

Here is the example he gave me.

I'm pretty sure I'm not going to move on to the next round but I hope anyone who reads this find it helpful.
