I applied through college or university. The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in Feb 2019
Interview
I spoke to a recruiter at a campus career fair and was contacted about an on-campus interview later that day. The on-campus interview was a one-hour technical interview consisting of resume questions and two coding questions (one short question about data structures and one long coding question). I was asked to do a second on-campus interview later that same day, but I didn't have time in my schedule to make it happen. Instead, they flew me out to their New York City headquarters two weeks after my first interview. There, I had a one hour technical interview consisting of resume questions and two long coding questions, a one hour interview with an HR representative to just get to know my personality and my hobbies, and a one hour interview from a manager (who asked me a quick technical question and talked about the job). Overall it was a very enjoyable experience and I had a lot of fun in the interviews. I was able to use my preferred coding language (Python), but I found that this is not super relevant because most of the interviews were done in pseudocode on a whiteboard. I used glassdoor to try and prepare for my interviews, but all of my questions were different from what was posted.
Interview questions [2]
Question 1
Suppose that we are given a binary search tree, where each node has a left and right child, and we want to add an attribute to each nod. We want to add an attribute to each node, "adjacent", that links the node to another node to its right, on the same level. For example, if you had a binary tree of 3 nodes (root node A, left child B, and right child C), A.adjacent --> Null, B.adjacent --> C, and C.adjacent --> Null. Design an algorithm that populates the adjacent field of every node in the binary tree starting with the root and give a runtime analysis.
Suppose you are writing a program that helps set up meetings between people in a company. Everyone gives you an unordered list of times in which they are busy. Given one of these lists, write a function that finds all the times in which they are free. Consider only one day at a time, starting and ending at midnight. Think about edge cases and how your code will handle them.
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
