BlackRock Software Engineer Interview Questions & Reviews

Interview Details Interview was a fair game. I decided not to pursue and cancel final round as I felt the mode of interviewing was too stressful/too much pressure for me personally.

I had extensive phone technical screen involving a lot of math and C++ questions. Was invited to in-person 7 or 6 hour interview. Parts of it were supposed to be video interviews with NYC managers and I personally do not wish to do video interviews, especially with people I will never have to directly work with. Also, I felt that having to find parking in a paid garage was too much trouble. The good thing, there was one hour lunch interview part and they were paying for this...not bad. Phone interview was with senior engineer/manager and he was kind of making it stressful--I didn't like it, prefer more calm and relaxed style of conversation.

They gave me infamous Monty Hall probability puzzle/paradox during phone screen...I disagree with "solution"--as many mathematicians outside the US. I had written code proves that "US solution" is wrong. So, I stand by this and felt this paradox shouldn't have been brought up since it does not have accepted solution in Mathematics community across the world. I rate overall interview experience as positive as they offered to buy me a lunch, was showed basic respect on their part.

Interview Details I submit my online application and got reply after a month. The interview was schedule after 3 weeks.

Interview Details First interview was a phone interview. The manager throw rapid fire questions and he tells you if you answered wrong.

Interview Details First Round on campus interview. And they called back the other day to schedule the next's day on site interview. The interview is in the afternoon so had to get up early to catch the flight. Too tired and not much time for lunch. No time for me to prepare.

Interview Details Got emailed for on-campus interview after talking to several recruiters on campus. The on-campus interview was very easy. Most of the questions were based on class experience and projects you have worked on in class which lasted about 30 minutes. The next day I was invited up to the SF office for a on-site interview. Interview was 4 1:1 45 minute interview with the vice-presidents of the different tech departments of Aladdin. The interviews varied depending on the person. One person just asked me about class and resume experience, ended up spending 30 minutes talking about the entire HTTP protocol and how PHP fits into the cycle as well as the idea of the internet. Interesting talk but had nothing to do with programming or my experience. The rest of the interviews were more standard - talked about class -> several software questions about design patterns, SQL queries, OOP, etc. I am writing "No Offer" because it has only been a week and I have not heard back from them yet.

Interview Details They are always the same question. The first question is list the data structure you know. The answer is Array, List, Heap, Queue, Stack, Hash, Tree, Graph.
The second question is how queue and stack work? My answer is FIFO, FILO.
The third question is Describe the different of array and list. My answer is array is fixed size, and list is dynamically allocated. And array access directly. List access from the first element to the data you want.
The forth question is how hashmap works? Take an example of how to use it. My answer is a.put("name", "123456");//key is name，value is sting 123456.

The fifth question is let you group the strings you see in many barkets. Actually, I don't understand this question very much. Many people say the answer is hashmap. While it seems that there are better answers. I don't know.

Then I heard the other people be asked write binary tree. How Virtual function works in Java. How to delete duplicate in an N size array with each element from 1 to n.

That's what I know about Blackrock. Their question is no longer changed. Hope everything goes well to you, guys!

Interview Details A very short on campus interview. The question is easy. We need to inverse a sentence without inverse the words. For example, "Carnegie Mellon University" to "University Mellon Carnegie". Then he asked about virtual functions in C++. This position needs some finance background. I think this is the reason that I was rejected.
