Zach, Global Data, Tokyo – volunteers across the globe in Singapore, Hong Kong, Princeton and New York. He volunteers as an English teacher to students with mental and physical handicaps, with an organization called Palette. "We all learned a lot from each other. There are borders between people of different backgrounds. When you break down these borders, you grow," Zach says. "It's inspiring to connect with the world."


Cristiane, Sales, Sao Paulo – tutors a group of students with Cidadão Pró-Mundo, a local NGO. "We believe that more than learning a new language, they are expanding their access to culture, education, and to the job market," Cristiane says. "The return we get from individuals and charities we work with, whether we provided them a fun afternoon or created them new opportunities that will have a lifelong impact."


Madison, Global Data, New York – a musician who offers her talent in music…and painting park railings. She refurbished a railing in Riverbank State Park, “Every time I ride my bike by the park, I think of how nice it looks now!” She also volunteers with Holiday Express, a traveling band that visits children's hospitals and centers during the holiday season. “Seeing them smiling and having a great time, talking about how much they look forward to seeing us each year--the volunteer work pays for itself!”

    Software Developer Interview

    Anonymous Employee in New York, NY
    Accepted Offer
    Positive Experience
    Difficult Interview


    I applied through college or university. The process took 5+ weeks. I interviewed at Bloomberg L.P. (New York, NY) in June 2015.


    Extremely smooth interview process.

    Start off with the application on their website. It was smooth and only a resume submission. After that I was emailed by Bloomberg to set up a phone interview which I did. The recruiter also shared a Hackerrank link for the interview. (if you are unfamiliar with Hackerrank I definitely recommend practicing on their website)

    Phone Screen (2 hrs):
    The interviewer called perfectly on time and was extremely nice. After testing the connection of the hackerrank session he asked about my experience which I had prepared and I described the tasks that I had worked on in my internships. Then he asked "Why Bloomberg". Definitely prepare a series of points for that as this is crucial to your interview. After that it was technical. Questions:
    - Given a set of arbitrary float numbers in an SQL table select only the ones that are exactly 4 decimal places
    - Remove arbitrary spaces from a sentence:
    eg: "The sky is blue " --> "The sky is blue"
    - Reverse an integer:
    eg: 3421 --> 1243

    I was then contacted within two days to schedule an interview onsite. The HR department is extremely efficient. They scheduled and paid for flights and hotel and they compensate you with a gift card as well.

    Onsite Interview (4 rounds):
    The onsite interview begins with the tour of the building. Its an amazing office. The tour ends in a room with the first set of interviewers who find you in the group of people and take you to your interview room where you will be for the rest of the day.

    Round 1 (2 hrs):
    2-on-1 interview. Interviewers are very very helpful. I feel like a struggled at times but they were encouraging and basically test you to your limit.
    First I was asked in great detail about my internship. Definitely prepare your background from your resume. They are extremely knowledgable and will delve into great details about past projects.
    The technical question was to design a stack with O(1) lookup for minimum element in the stack. They first make you optimize your design till they are satisfied and then you have to write code for push, pop.

    Round 2 (2 hrs):
    Again 2-on-1 interview. These interviewers were probably the ones who were supposed to be harsh. "Why Bloomberg". Be prepared! Then they asked about database management systems. Why is is better to have that over just creating text files? But he was never satisfied with my answer but I kept trying to resolve his questions without giving up. I think that is crucial. Then I was asked to design an address book which you can use to:
    a) Get the the info of a person from the name
    b) Get the info of a person from a number

    Numbers are unique but names are not. They will ask you to heavily optimize your design (most optimal design: use hash tables with key as the the name or number and value as a pointer to the location of info with binary trees to handle collisions)

    At this point I noticed people being escorted out. So basically if you don't pass your first two rounds then they walk you out of the building. If not then you have an HR and managerial interview.

    Round 3 (45 mins):
    An HR lady will interview you. At this point you've basically passed and they're just checking a personality fit for the job. This interview was mostly just HR related. Finding out status of visa etc. Expected salary? Where else have you applied? Do you have an offer? etc etc. Keep the answers to those to a minimum. Do not mention more than 1 or 2 companies.

    Round 4 (1 hr):
    Managerial interview was by far the most relaxed interview of all. It was basically just a conversation while delving into details about the past projects. I was also asked why I chose my internship and where I applied AND where I got accepted (that was definitely a little unexpected). We discussed my goals at Bloomberg and also extra curricular activities that I would like to get involved in. When were out of time she thanked me and walked with me till the entrance of the building.

    I was contacted within 3 days of the onsite interview with an offer over the phone. The official offer letter was sent by email a few days later.

    P.S. The interview process took around 40 days for me because I could not make it for the recommended onsite interview date for personal reasons and had to schedule for a later date.
