Financial Sales and Analytics Interview (Positive Experience; Average Interview)
I applied online and the process took 2 weeks - interviewed at Bloomberg L.P. in July 2014.
Interview Details – Applied online. Started with a very short 10min phone screening with HR, and quick online personality test.
Next round was an onsite interview at their NYC HQ, which included a terminal demonstration, tour of the building, and back to back interviews with two people from Sales & Analytics - 30min each. Standard questions - i.e. Why Bloomberg x100, why finance, basic behavioral questions, tell me recent news story, Bloomberg's competitors, etc.
Last round was a job shadow with a current analytics member (be sure to ask a lot of questions to show your interest) and a one-hour interview with two managers. Similar questions as the previous round + a sales role play for a phone app.
Interview Question – Sell me your favorite phone app. Answer Question
Financial Software Developer Interview (Positive Experience; Difficult Interview)
I applied online and the process took 2 months - interviewed 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 Question – 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). View Answer
Negotiation Details – I did not do any negotiations. I accepted the offer for some time in the future since I need to resolve the visa part.
Financial Software Developer Interview (Neutral Experience)
Interviewed at Bloomberg L.P.
Interview Details – Had two round interview... first round was very straightforward, asked typical data structure, graph search, and object oriented questions (linked lists, depth first search, memoization, classes). Second round was much harder, with algorithmically complicated coding problems (the naive solution was usually easy, but the interviewer would then press on for a much more difficult solution)
Interview Question – Counting the number of anagrams of one string in another string View Answer

Financial Sales and Analytics Interview (Negative Experience; Very Easy Interview)
Interviewed at Bloomberg L.P.

Financial Sales and Analytics Interview (Neutral Experience; Difficult Interview)
I applied online and the process took 3 weeks - interviewed at Bloomberg L.P. in June 2014.
Interview Details – Apply by the website.
Was contacted by email for a first interview by phone with one person of the team. Questions about Bloomberg. Work situations ...
2nd interview with 2 managers for 1 hour. Same question that everybody (technical and sales, why bloomberg, play role ...).

Financial Sales and Analytics Interview (Positive Experience; Difficult Interview)
I applied online and the process took 4+ weeks - interviewed at Bloomberg L.P. in May 2014.
Interview Details – Step 1: Personality Test: Gives you 60 character traits and you have to rank which ones are most like you, kind of like you, slightly like you, and then the same for not like you.
Step 2: Phone Interview: Simple questions about resume, why bloomberg, and the position. make sure you know about the position, and that it is about interfacing with clients/sales in addition to the finance aspect. They're trying to see if you're a good fit/that you really want Bloomberg
Step 3: In person: 1 hour tour of facilities, terminal demonstration, and then two 1 on 1 interviews. show your interest throughout. one on one is with someone from sales/ someone from analytics. Sales will ask you about sales experience/sales based questions, and analytics will ask you about the "why finance" side of things and some questions about motivations for the job.
Step 4: 2 on 1 with 2 managers in the analytics department. Much more difficult. Ask some critical thinking questions, are constantly on their phones trying to throw you off, and somewhat rude. Don't be phased by this; stay positive and polite and answer everything.
Interview Question – why bloomberg?
what's more important in sales? the client or the product?
what do you know about the position?
what is one story you have been following in the markets?
what is the biggest misconception about you?

Financial Products Sales&Analytics Interview (Neutral Experience; Average Interview)
I applied online and the process took 3 days - interviewed at Bloomberg L.P. in March 2014.
Interview Details – I applied a position in Beijing office. Hong Kong office HR interviewed me. All basic behavior questions: Why Bloomberg? Why you? Then followed up with a role play - giving a cold call and sell a product to him. Last was Q&A section. He did not give much information on my questions, and said "that's so far you need to know" . Got the second round offer, but somehow didn't proceed in the end. The HR was a bit mean and unprofessional, which ruined my good impression about Bloomberg.
Interview Question – Role play Answer Question
