Software Developer at Bloomberg L.P.

Declined Offer – Interviewed in Charlotte, NC Jan 2013 – Reviewed Mar 4, 2013

Interview Details – Initially they had an on-campus interview with a couple of technical questions about trees and hashing. I thought I had bombed but I think they saw that I was constantly thinking so I got a second interview. This one was all technical with whiteboard coding and a week after I got an offer.

Interview Question – Given two trees over the same set of nodes, what is the longest path they have in common?   Answer Question

Interview Details – One Phone Interview and one on-site interview.

The phone interview is about two weeks after I submitted the resume online. There was many basic questions about algorithm, data structure and design issue such as the difference between the implementation of hash-map and map. No coding is required.

After the phone interview, hr contacted me for on-site interview. But I haven't take that yet.

Interview Question – Design an data structure for several real applications   Answer Question

Interview Details – I submitted the application online, and they sent me an email asking my availability for a phone interview. The interviewer asked me about my past projects, etc. If I remember correctly, he asked me about multithreading vs multiprocessing and other related material. He asked me a dynamic programming question which wasn't very hard but I didn't get it nevertheless. The rest of the interview questions wasn't hard and was basically about simple sorting stuff and data structure. The onsite interview was held in their ny office. I was stuck on the first question which only required very basic math. It took me about 5 min just to understand what was going on because I couldn't picture the situation the interviewer described. After that, I don't remember much because I completely lost interest and just tried to get it done with.

Interview Question – how different processes communicate with each other
the advantages and disadvantages regarding multithreading vs multiprocessing
given an input of integers that represent stock prices, how to get the best buying and selling price (notice you can only sell after you have bought the stock)

Interview Details – You will have a number of phone screens, possibly from completely different groups. You may feel that you did well or poorly on some but do not be surprised if the opposite groups that you think would be calling you back, in fact do. If you are invited to an onsite interview you will start by being interviewed by some of your co-workers. This process unfortunately is to show the interviewer how smart they are and not so much about finding out what you really know. As you make it through each hurdle you will be interviewing with people higher up in the management chain. If you make it to a point where someone from HR comes in to talk to you about the compensation, you can feel pretty sure that you will be receiving an offer assuming that you pass their drug test and background check.

Interview Question – Usually some brain teaser which will have no bearing on the type of work that you will be doing. It is simply asked to boost the interviewer's ego so that he can appear smarter than you. Sad, I know.   Answer Question

Negotiation Details – I was given an offer and I could either take it or leave it.

No Offer – Interviewed in New York, NY Jun 2012 – Reviewed Jun 17, 2012

Interview Details – I submitted an application with my resume. A week later, I received an email to take an IQ test within 3 days. I took the IQ test, it was pretty long and the countdown timer didn't help. I think I guesstimated about 2 questions. Scheduled a phone interview with an employee who is also a Software Engineer. Here's where it started making me uncomfortable. He would ask technical questions about coding, just like all the other software companies ask, with the exception that when I would hesitate to think or ask for some time to think it through, he giggles and laughs. Or when I would ask for a clarification for his question, he would again, giggle and laugh. After about 15-20 minutes of this torture, I asked him what was so funny, he said the situation is funny because usually other applications know what he is talking about. So, I'm not a CS major but I decided to give the position a shot because I have some programming experience. At the end of the interview, I've already decided in my mind that I don't wish to work for Bloomberg. He asked me if I had any questions about the position or the company. I said no, I have no questions. He then says to me "so you know EVERYTHING about the position and the company. You have absolutely no questions." Something to that effect. (Emphasis not added after the fact. He actually emphasized that word.) I explained to him that after this interview I decided to not pursue the position with Bloomberg. He then responds by saying that not everybody is suited for the position and that the interview is a two way interview. I agreed.
