Bloomberg isn’t just a place where you come to work every day. We’re measured by our contributions, and not by titles. We don’t need an open-door policy. We sit in bullpens, shoulder-to-shoulder.
We take care to foster a culture of diversity and community, and we are dedicated to our employees’ well-being, offering generous benefits, training and opportunities for meaningful volunteerism.
Through community service and charitable giving, we strive to make an effective impact on the community through a range of programs in the areas of health, sustainability, literacy, social welfare and the arts.
We are also a sustainable company. We’re always finding greener ways of working. Like our new data center in New York, which is the second data center and the 17th building in the world to earn LEED – Leadership in Energy & Environmental Design – certification. It recognizes best-in-class building strategies and practices.
And we’re helping others to be more sustainable, too. For instance, we recently made a major investment in analytical tools for the green bond market, which finances projects that address climate change.
When Michael Bloomberg founded this company, he made giving back a part of its DNA. As we’ve grown, we’ve been able to do more and more for the world around us. Today we devote an incredible amount of resources, including our time and talents, to bringing out the best in our communities. Moreover, our profits fuel the work undertaken by Bloomberg Philanthropies, whose mission is to create better, longer lives for the greatest number of people.

I have been working at Bloomberg L.P. full-time (More than 3 years)
Pros
Amazing office, great ambiance and vibes, transparency, free food
If you perform well, they will invest so much in you from knowledge to mental health wise
Philanthropy
Diversity
Great culture
Dynamic work, never dull
Cons
Really I don't have much. Just the fact that if you quit, even if for personal reasons like do a MBA or a family matter, it is impossible to go back in

Application
I applied through an employee referral. The process took 3+ months. I interviewed at Bloomberg L.P. (New York, NY (US)) in May 2018.
Interview
I applied online. Two days later I got an email to schedule a phone interview.

Phone Interview
The interviewer was on time and quite friendly. He asked my a few questions about my interest in the company and why I thought I was a good fit. We then went through 3 fairly simple technical questions.
1. There are two streams of integers that should be captured and stored in the order they come in. Implement a way to retrieve the n most recent integers stored.
This was fairly simple to implement using a Linked List.
2. Given a binary tree, return the left-most node of each level in the tree.
I used an altered implementation of Depth-First-Search where you keep track of the current depth and stored left-most values in an array.
3. Implement a dynamic internet browser history system (keeping only 5 items up).
Here I panicked a bit and started doing an LRU cache, but managed to iron out the overkill, ending up with a custom implementation of a fixed-size Linked List.
We then concluded with questions I had for him. My questions we about the culture in the company, his team's duties and any philanthropic work he's been involved in during his time there. This interview took about 50 minutes.

After a very long delay, I was invited to interview on-site at their Headquarters in New York. Bear in mind that I applied for a position in London, but interviewed with the NY folks.

On-Site Interview
This part of the interview was split into 4 rounds. Each round had the same structure. We began with a short discussion about my interest in the company, my background and projects. Depending on the interview, we did technical or HR-related questions after that and then concluded with any questions I had. Each interview was 1 hour.
Technical Rounds (1 + 2)
1. Given a marathon route with markers that track runners' progress as they cross them, implement a system to keep track of the leaderboard.
I used an array of Linked Lists, one for each marker, as well as a HashTable to move runners around the markers. The interviewers helped make this as optimal as possible. We discussed trade-offs using Binary Search Trees instead of the lists.
FOLLOW UP: Implement a notification system that pushes a notification every time a specified runner, the three runners behind them or the three runners in front of them change their position in the leaderboard.
Okay this was pretty hard because I didn't know which part of the problem they wanted me to solve. I got stuck but I eventually figured out. Used an ArrayList of lambda expressions that pushed the notifications, triggering all of them in sequence when a runner crossed a marker. Even though they had to help me through it, they seemed pleased with my response.
2. Given a gym space on a grid, where spaces can be open, blocked or representing a gym equipment being used, we're looking to work out at the equipment on cell A, then use a yoga mat, then go to the equipment on cell B. Find the optimal place for the yoga mat.
This was a pretty weird question. I initially suggested Dynamic Programming. The interviewer said that was cool but we could solve it in a more elegant way. After a discussion about the way search algorithms work, I implemented a two-way Breadth-First-Search from both points, and returned the first point of contact. The interviewer seemed pleased with the response.
3. Implement the classic game Snake.
This was a fun one. I used a Linked List to store the snake, having O(1) operations for each of the interviewer's requirements from the start. He seemed very pleased with this answer. We had a great discussion about special cases and debugging the game to account for different use cases.

HR Interviews (3 + 4)
The first was a friendly session of HR questions about leadership, teamwork, cultural fit. It seemed that the interviewer was trying to make sure I was a good cultural fit. Make sure to practice behavioral questions for this round and know the company + your own stuff.
The second interview was with a Senior Manager in the Engineering department. It was more about my specific interests in teams, my career prospects with Bloomberg and the different paths I can take if I work there. This was the time to let all that industry knowledge shine.
Overall a great experience. Very well-organized, extremely friendly, knowledgeable and professional.
