    Financial Software Developer Interview

    Application Details

    I applied through college or university. The process took 3 daysinterviewed at Bloomberg L.P..

    Interview Details

    Had four on-campus interviews following a career fair--three technical and one with an HR guy. I was allowed to use any language. There were six questions. Two were about implementing some common function, such as a String class constructor. One required partitioning a list around a given element. One required merging two schedules that might overlap in some parts into one schedule. The last two are described below.

    Interview Questions
    • You're given a binary tree--not necessarily complete or proper--and you need to give each node a "friend" pointer that points to the node to its right in the tree. This node is on the same level but is not necessarily a sibling, which makes the problem a little tricky. The friend pointer of the node farthest to the right on each level should be null.   View Answer
    • You're given two arrays of the same size filled with positive integers, and an integer 0 <= N <= 255. You need to determine whether N can be written as the sum of some number from the first array and some number from the second array.   View Answers (2)

    I applied through an employee referral. The process took a weekinterviewed at Bloomberg L.P. in September 2014.

    Interview Details

    Initial on campus technical interview, followed by a second technical interview the next day, followed by a technical/fit interview and an hr interview the next week. Whole process was over in a week. Technical interviews were with two software developers at a time. In the technical interviews, was asked between 2 and 5 questions. Interviews are difficult, but interviewers are nice and provide hints when necessary. Recruiter was very friendly.

    Financial Software Developer Interview

    Anonymous Interview Candidate in New York, NY
    Anonymous Interview Candidate in New York, NY
    Application Details

    I applied online. The process took 2+ monthsinterviewed at Bloomberg L.P. in June 2014.

    Interview Details

    From the online application (bloomberg website) to the phone interview took around 4 weeks (a first interview was scheduled within 2 weeks but the interviewer didn't call so we rescheduled). The phone interview was quite straightforward and I was asked the following questions
    1- Kind of a strange question. Generate all 3-digit combinations of 1-9 but not repeats in the sense that if you have 123, then 231, 321, etc. are not allowed. [nested for loops]
    2- Reverse a given sentence (no use of library methods, arbitrary spaces between words). Make it faster. [start at the end and find and print words one-by-one].
    3- You are given a 3L and a 5L container and unlimited supply of water. How to make 1L?[I found a longer solution but the short on is pour 3L into 5 twice.]
    4- A program/algorithm which given mL and nL buckets figures out how (if possible) make kL. [we discussed the solution and the interviewer was nice and gave me a hint. Its a DP problem].

    The next day, I received and invitation for on-site interview. The travel schedule part was straightforward and convenient.
    I was invited to the NY office. There was a group of around 30 people like me. They hold you for a few minuts to issue a security badge. Then there is a tour about all the 31 or so aquariums and fishes at bloomberg. Eventually, there is breakfast and then the interviews come find you. There is 4 rounds of interview. Rounds 1-2 are technical, 3 is management, and 4 is HR.
    Some questions I remember:
    1- Find shortest path on a chessboard from low left corner to top right. You can move right and top only and some cells are inaccessible (DFS).
    2- You have sorted arrays A and B with sizes m and n. Assume at the end of array "A" you have "n" empty slots. How to merge with minimum number of operations (start at the end instead of beginning). Prove it works (induction).
    3- Some runners running in a field with some "k" sensors. We get events of runnings locations. How to print the top "m" runners? (array of lists or hash table of lists depending on the location of the sensors. each list is one sensor). Some questions on how to identify the ordering within each list.
    4- CPU Cache implementation. How to implement the least frequently used procedure.
    5- Scheduling some jobs over "m" servers. Centralized vs distributed implementation? How to implement.

    The management interview was interesting and I liked the two managers. HR was fine too. I did not do any negotiations.

    Interview Questions
    • The chessboard problem. I first mentioned BFS and use of a Queue but the interviewer kept asking about some data structure with less memory that I could extract due to the simple structure of the graph. I did not understand what he meant. I eventually mentioned DFS and proved it works uses less memory.
      The cache problem took a long time. I kind of though I failed it at some point. I had no prior knowledge of the topic since I am not a CS guy. I eventually, used an array to store the access time to different items and O(n) search through it to find the least frequently used one. The interviewer did not raise the complexity. He wanted me to write code on a paper (which is hard, esp. in C).

    Interview Details

    I was referred by another employee, so the process was fairly easy. I just had to submit my resume and a cover letter and then the hiring process and interview was fairly straightforward and easy. There was a phone interview, a Skype interview, a one-on-one and then I was offered the position. Overall, it was a pleasant experience.

    I applied online. The process took 3 weeksinterviewed at Bloomberg L.P..

    Interview Details

    Straight forward. A few days after I applied online, I got an email to set up a 1st interview with HR. That interview was 10 minutes and basic "why bloomberg?" "why looking to leave current position?". He said someone would follow up for the next round. Next day got an email to set that up. There were probably 50 of us there, we split up and some had a building tour while the others interviewed with 1 sales person and 1 analytics. Mostly fit/behavioral. Then came back a week later to shadow someone on the help desk and do an hour interview with someone in senior management. Offered the next day

    Global Customer Support Representative Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied online. The process took 3 weeksinterviewed at Bloomberg L.P. in August 2014.

    Interview Details

    The interview was fairly standard, though they seem to try and test you subtly. After applying online, I was invited to speak with someone from HR who tested waters. She asked questions such as why I was interested in customer service, Bloomberg, and what my goals were---in short the interview standard questions. A week after our phone call, I received an email inviting me to schedule an interview within the next two weeks. Replies were long in coming and it took reaching out every 4 days to finally schedule an interview. I did so and went in to meet with them in person.

    The in-person interview was three part. In a unique twist, they start off by letting you get a taste for the actual work by allowing you to briefly observe how the work is done. This secession was followed up with a formal interview where questions to determine your company fit really and appropriateness for the role are asked. After I was ushered to meet more of the team and the manager who asked mostly behavioral questions (what is your greatest weakness, strength, how would someone describe you, what do you like best about customer service, where do you see yourself in 6 years, ect...). Response then came via email after about a week.

    Three things will make you do well:
    1) Prepare- research the company, look for interview questions and try and prepare answers, and speak with people who've worked there if you can. Definitely check their wiki and know who their competitor is.
    2) Be Yourself- They hate canned responses. If any resource suggested answering with a particular reason or weakness, take the gist of it but spin it into something original.
    3) Be Persistent - Treat the whole process as a test. They want to know how you react to being ignored, being stressed, pushed, ect... Be polite, try to keep calm, and take your time to think of your responses. Do not try to answer a question simply out of a need to answer. Be respectful and honest.

    Interview Questions
    • None of the questions were difficult or unexpected. Most followed the standard script with a few situational questions to test your customer service skills. Many dealt with how you would react to an angry customer, what to do when you're not sure of the answer to a customer's call, and how you react to stress.   Answer Question
