I applied in-person. The process took 2 days. I interviewed at Bloomberg (New York, NY) in Feb 2017
Interview
telephonic interview 1 hour:--
what will you do if number is greater than current max size in the language - (use array to store the number)
asked me to write a program with to add two integers store in an array format. (not that easy as it looks , took me whole 15 mins to write this...)
we went over hashmap and hashset in java. why it is O(1) to for both. Also how hashcode gives location of element in the array in hashmap, what operation is performed to get it. and so on....
Interview questions [3]
Question 1
given a method which had for loop with 100,000 iteration and calling it to some method with heavy call ( for that exercise they used sleep). all the results from the method call stored in array. how will you improve performance.
question :-- how Messaging framework work. what if two brokers are connected and if one publisher publishes on a QUEUE and two subscribers on 2 different brokers waiting. how message is delivered.
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.
Fairly simple. Phone call then onsite. For onsite it was 10 min office tour follow by 1 hr interview then 1 hours system design and 30 mins manager interview. Interviewers were nice and the recruiter was accommodating.
5 rounds first 3 being leetcode coding ones and the last 2 being behavioral. The first three are the hardest asking mainly taggeed questions and the rest are not that bad
