Software Engineer Interview

I applied through college or university and interviewed at BlackRock.

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 Question – Actually no difficult questions. But they like recursive I think.. Try basic recursive questions and DP questions.   Answer Question

I applied through an employee referral and the process took a day - interviewed at BlackRock in April 2014.

Interview Details – A 30 min phone interview followed by a on-site interview. I failed at the first round. They only asked behavior questions in the phone interview. They go through two big projects on my resume. Then they asked me how to use HashMap in JAVA, which is to override the hashcode() and equals() method. Equals method is used to avoid the collision.

Interview Question – The interview is so easy, no technical questions   Answer Question

I applied through college or university and the process took a day - interviewed at BlackRock in September 2013.

Interview Details – I have an on campus interview. I didn't get any technical questions. The recruiter first introduced the company for me and asked why I was interested in BlackRock. Then he asked me about the most interesting class I have taken. We have talked about the class and the project I have done for that class. Then he asked me the most tricky bug I have solved. At last, he asked me a simple question about array.

Interview Question – Tell me about the most tricky bug you have encountered.   View Answer

I applied through college or university and the process took 1 week - interviewed at BlackRock in January 2013.

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.

Interview Question – Inverse a sentence.   View Answer

I applied through college or university and the process took 4+ weeks - interviewed at BlackRock in February 2013.

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!

I applied through college or university and the process took 3+ weeks - interviewed at BlackRock.

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 Question – Write a query that would join two tables and collapse them on one attribute.   View Answer

I was asked to implement a simple binary search method and asked some other basic questions about data structures, eg. hashmap, array, linked list. Also why blackrock?
