I applied online. The process took 2 months. I interviewed at Bloomberg (Londres, Angleterre) in Nov 2018
Interview
Two telephonic rounds followed by two rounds on-site.
Telephonic round1: One Leetcode medium and one leetcode easy. Interviewers were pleasant and I enjoyed interviewing.
Telephonic round2: Two Leetcode medium. Interviewers were pleasant and polite. At this point I had a very good feeling about this company.
Onsite round 1: 1 leetcode medium but the interviewer for some reason constantly interrupted me while I was solving the problem with aggressive questioning on every line of code that I wrote while I was still in the process of formulating the solution. This put me completely off balance throughout the interview due to which I couldn't finish coding the solution. Due to this round I had bitter feeling about the company's culture and the kind of people they hire.
Onsite round2: One leetcode medium. This was a DP problem. I came up with a solution using memoization and implemented it. The memoized version had the same time complexity in terms of big O notation as the DP solution. But the interviewer kept arguing with me that the memoized version had "more time complexity"(his/her words) than the DP solution. I told them that of course some constants might be more and also the memoized version may cause stack overflow but in terms of big O notation, the time complexity is the same.
The pantry in this company has security guards deployed which I found to be quirky.
Terrible communication. Got passed between 3 different recruiters all of whom gave specific dates for updates and blew past them. Descriptions of what would be covered in the interviews are wholly inaccurate (don’t bother reading the PDF they sent to “prep” you, almost none of it came up in any of the 3 interviews I did with them.)
Interviewers themselves were decent but clearly had exact “right” answers they were looking for. What’s the point of a leetcode question where there’s only one way to implement it? What’s the point of a system design interview where you’re having a candidate parse through a complex system that they clearly already know everything about and are just looking for 1-2 EXACT modifications to check off their boxes? Was there even a right answer? I genuinely don’t know what this company was looking for. Waste of time, waste of effort, waste of resources. Avoid, avoid, avoid
Interviewed with two separate teams. Coding rounds. Leet code style question. The interview went on for 1 hr. Waiting for the next steps. The seem to like link lists and arrays
