    I applied online. The process took 4+ weeksinterviewed at Bloomberg L.P. in May 2010.

    Interview Details

    I applied through an online job website. And I was contacted by their HR staff. She was very efficient and was able to answer my queries. I was told the interview date and time. On the day of the interview, I was greeted at the hotel lobby by the recruiting manager. When my time came, the interviewer himself came to take me to the room. The following were the questions asked to me:
    1) Write the function prototype for strcmp
    2) Write the implementation for strcmp - there was a mistake in that and they made me point it out.
    3) they gave me a structure. struct A { char a; int b}; what is the size of it? (Ans: 0's padding concept)
    4) how will you count the number of 1's in an integer? write a function to do that (Either use mask, or bit shifting)
    5) polymorphism
    6) y do u use virtual functions
    7) what is inheritance
    8) since i had put linux experience on the resume, they asked about sockets, TCP/IP and UDP sockets.
    9) which kind of socket do you use for what application?
    10) Mutexes. i was asked return type of trylock() and how does it work?
    11) And describe how to set up a client and server connection? (what are the various function calls you use to set up a client-server?)
    The questions were not that tough but I dont know why, I was not able to do well. The interviewers were good and knew what they were looking for in candidates. Overall, it was a good experience for me.

    I applied online. The process took a weekinterviewed at Bloomberg L.P. in March 2010.

    Interview Details

    I applied to the position on Bloomberg's careers website and got a call from them shortly. The first round was a telephonic interview and I spoke to two developers who had been working there for 3-4 years. The interview was about C++ and basic data structures and algorithms. The questions were pretty simple. I just messed up that interview and I didn't answer very simple questions that were shot at me. What they were looking for was proficiency in C and C++. Browsing through standard interview questions available online would probably be the best way to prepare. The interviewers seemed to be very nice and cordial. They said that the successful employees at Bloomberg were those who were flexible, dynamic and could get things done as quickly as possible rather than plan very well. Unfortunately, I messed up the interview although I consider myself a very good programmer and had the relevant experience.

    I applied online. The process took 1+ weekinterviewed at Bloomberg L.P. in February 2010.

    Interview Details

    I applied on their careers site. Got a call after a couple of day. I was asked to take a technical onilne test. I chose C++ as my language. The tests were a little bit simple. Than after that there is a phone interview. That is not so difficult. But the bad thing is that the interviewee is an indian. I have some problems in listening his English. I think that is the reason I failed in the phone interview.
