    Application Details

    I applied online. The process took 4 weeksinterviewed at Bloomberg L.P..

    Interview Details

    I filled out an application on the company website and was contacted via email to schedule a phone interview. This took place two or three weeks after applying. Eight days later I had the interview.

    The interview was technical, consisting of story problems to solve. Some of the questions had multiple parts. Because the interview was meant to last 45 minutes, there was time pressure and the recruiter would not move on to the next question until I had answered the current question to his satisfaction. When I suggested a less efficient solution for a problem, he would not move on until I found his solution. If I struggled with a question hints or clarification would be given.

    Interview Questions
    • You have 25 horses and a racetrack where you can only race 5 horses at a time. You can only get qualitative comparisons of horses (e.g. horse A is faster than horse B), not actual race times. How can you determine the three fastest horses with the fewest races?   View Answers (7)

    I applied online. The process took 2+ monthsinterviewed at Bloomberg L.P. in December 2013.

    Interview Details

    Applied Online...

    Phone Interview.. Not difficult.
    Question 1: Why make data members private and access them using getter and setter methods when you can access them directly by making them public.
    Question 2 : Given stock prices of n days. Find when to buy and when to sell stock in order to gain maximum profit
    Question 3 : Given an array of size greater than 'x' and a range 0 to x . Find duplicate elements in the array. Hint. You can destroy the array but the solution should use O(1) space and O(n) time where n is the size of the array.

    On Site Interview:

    Interview 1 :
    Interview with 2 software developers
    Started with some questions related to my projects
    Q1 : Diamond Inheritance Problem in C++. Use of virtual keyword. And how are things handled internally. Basically checked my understanding of vtable

    Q2 : Can you use virtual keyword with destructors?

    Q3 : Given heads of two linked lists. Find if the two linked lists intersect.
    Solution should not use extra memory.

    Q4 : Reverse linked list. Tested concepts of double pointers, pass by value and pass by reference.

    Interview 2 :
    Interview with 2 software developers
    Q1 : In what case would you use BST over a hash table..
    Q2 : Insertion in BST
    Q3 : Find 'k'th smallest element in BST. What extra information would you require here
    Q4: Given a string which has a lot of spaces beween words . Remove these extra spaces in the string
     eg: " I love New York " --> "I love New York"
    Q4 : You get an input in the form [2 lowercase characters , A number] .. eg [aa,10] , [bd, 12]..
    Given a two letter input, find the last 10 numbers associated with the string..
    Design a data structure to implement this without using STL. Basically I was asked to design a hash function.

    Interview 3 :
    Interview was with a project manager

    Q1 : Find the first distinct element in an array
    Q2 : C++ does not have byte datatype. How would you create this datatype.
    Q3 : Lets say I have a code currently executing on my machine. I overwrite the code with a newer version. But the older version is still executing. Why do you think this is happening.

    Interview 4 :
    Interview with HR
    General HR Interview

    Interview Questions
    • Given heads of two linked lists. Find if the two linked lists intersect.
      Solution should not use extra memory.

    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).

    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.
