Extremely smooth interview process.

Start with the application on their website. It was smooth and only required 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 hours): The interviewer called perfectly on time and was extremely nice. After testing the connection for the Hackerrank session, he asked about my experience, which I had prepared. I described the tasks I had worked on during my internships. Then, he asked, "Why Bloomberg?" Definitely prepare a series of points for this, as it is crucial to your interview. After that, it was technical. Questions:

• Given a set of arbitrary float numbers in an SQL table, select only those 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 onsite interview. 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 a tour of the building. It's 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 hours): A 2-on-1 interview. The interviewers were very, very helpful. I felt like I struggled at times, but they were encouraging and basically tested me to my limit.

First, I was asked in great detail about my internship. Definitely prepare your background from your resume. They are extremely knowledgeable and will delve into great detail about past projects.

The technical question was to design a stack with O(1) lookup for the minimum element in the stack. They first make you optimize your design until they are satisfied, and then you have to write code for push and pop.

Round 2 (2 hours): Another 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 it 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 that you can use to:

• Get the info of a person from their name
• 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 the name or number as the key and a pointer to the location of the info as the value, 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, they walk you out of the building. If not, you have an HR and managerial interview.

Round 3 (45 minutes): An HR lady interviewed me. At this point, you've basically passed, and they're just checking for a personality fit for the job. This interview was mostly just HR-related. Finding out visa status, 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 one or two companies.

Round 4 (1 hour): The managerial interview was by far the most relaxed interview of all. It was basically just a conversation while delving into details about 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 extracurricular activities that I would like to get involved in.

When we 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.
