I applied through college or university. The process took 4 days. I interviewed at Bloomberg in Feb 2019
Interview
I got a campus onsite interview directly in our school. Day 1 is the first round (1 hour), where I was given two coding questions. Right after that, the interviewers told me I passed this round, and scheduled the next interview the next day. In the Day 2 interview (1 hour), I was also given two coding problems, and I passed that, and scheduled the final round. The final round was scheduled two days later, which included one hour manager interview and half an hour HR interview. One week later, I received a phone call about the offer.
Phone screen went very well, i passed to the onsites and they gave me the problem statement and i proposed a sub-optimal solution. They told to me come up with more optimal solution and didn't give me much time to think about it. They got impatient and gave me a hint. I figured it out and solved the problem, but apparently they thought I needed hints, which I didn't ask for.
15 minutes talking about resume, 45 minutes for 2 medium leetcode style coding questions (using code share), the interviewer was very friendly and communication is even more important than passing all test cases.
Overall, it was a positive and professional interview experience, though the interviewer was on the stricter side. Unfortunately, I was dealing with an illness and wasn't able to prepare as thoroughly as I wanted to, which left me feeling a bit off throughout the conversation. Despite not feeling my best and facing a tough interviewer, the process was well-structured.
