I applied online. The process took 2 weeks. I interviewed at Bloomberg (London, England) in Jan 2017
Interview
Contacted by a recruiter asking for my CV. Had a phone screen followed by an onside interview. During the phone screen I was asked a DAG question - to construct all different paths from source to target.
Interview questions [1]
Question 1
In a Directed Acyclic Graph print out all the paths from a source node to a target node
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.
