I applied through an employee referral. The process took 3 weeks. I interviewed at Bloomberg (New York, NY) in Apr 2018
Interview
Phone interview with brief questions about my resume. A few days later I was invited for an on site interview. I had two one hour technical interviews. Since they didn't go so well I was escorted out following these.
Interview questions [1]
Question 1
Phone interview: 1) Code up merge step in merge sort. 2) Conceptually describe how you would implement an LRU cache.
On site: 1) Extremely tricky question I am still working on! 2) Implement in-order traversal of a binary search tree. Implement a schedule that takes as input some number of appointments within a 24 hour period and outputs all the free blocks of time.
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.
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.
