I just got done with a Bloomberg phone screen for an entry level position a few days ago. First 10 minutes of the interview was talking about a particularly challenging part of one of my projects. The remaining 50 minutes were spent on two technical questions.
The questions I was asked were:
- Modified Two Sum - https://leetcode.com/problems/two-sum/ (find all pairs that sum up to K and print them out, not return them)
- Sort String by Character Frequency - https://leetcode.com/problems/sort-characters-by-frequency/
The interviewer's explanation of problem 1 was very vague, and he was pretty unclear about the constraints he wanted. When I kept asking him about different edge cases and constraints (e.g. what about duplicate pairs?), he kept answering, "It's fine. Don't worry about that - that would be too complicated". He didn't even want me to code up the second one, just explain what I would do.
I was able to implement both in the most efficient way possible (O(n) runtime for both). I feel as if I lucked out extremely hard with these questions, especially after seeing some of the other questions people were asked. However, I feel like my interviewer didn't really care because of all the times he kept saying not to worry about edge cases and at times, he seemed to space out.
Regardless, I was able to get an onsite booked for the coming month!
