Difficult Interview

Application

I applied online. The process took 3 weeksinterviewed at BlackRock (New York, NY).

Given a online technical screening then came in for super day. Online screening was relatively simple, was given two questions on the level of "given a string check if its a palindrome". Super day interview consisted of anywhere from three to five interviewers in an intense technical interview for several hours.

    Interview

    I had an email with a recruiter to set up a phone call with a senior engineer. After that initial phone screen I heard nothing back from the company. I did some follow up with research about one of the topics discussed in the interview which the recruiter was impressed with but still heard nothing after that.

    Interview

    I submitted my application online, and I was invited for the first round telephone interview after about a week. The phone interview was entirely behavioral and I think it went alright. I am waiting for the results for that, which should take about a week. The next round should involve an in-person technical interview. Since I am still waiting for the results, I have indicated that I did not get an offer.

There were 3 interviewees for this position on my day of onsite interview. Each of us get three 1on1 interview, with 45mins each. They ask a lot about JAVA. Really, be sure to prepare as specific as possible about java.

    Interview

    I had my first technical interview over the phone where the interviewer shared a document for me to code. It was not a hard question. I was not very well prepared for coding on the stop when someone was looking at my process. Be able to code easy questions under pressure.

    I applied online. The process took 4 weeksinterviewed at BlackRock.

    Interview

    I applied online and got an email to schedule a phone interview a few weeks later. The phone interview was 30 mins and we went over my resume, internship experience etc. Brief question about set, list and map. I was then called up for a 3 hour in person interview in NY with 4 rotating interviewers. Questions ranged from: what do you know about the company, why this position, tell me about yourself to more detailed questions on programming knowledge and previous projects. They were nice and asked questions related to the things you said for example, "you mentioned abstract classes and interfaces in java, can you tell me the difference". Difference between C++ and Java. Look at this piece of code and tell me what it does. Write a function that does ... A brain teaser. They also give you a chance to ask questions.
    I wrote no offer, since I am currently waiting to hear back from them.

It has 4 people, much more about the resume, some conception and simple algorithm. The algorithm part is very easy, but they like to ask some conceptions. From database to normal java conception(I told them I like to use java)

    I applied through college or university. The process took 4+ weeksinterviewed at BlackRock (New York, NY) in December 2014.

    Interview

    They came to school for info session, then I applied online. After about a month time, I was invited for a phone interview. It wasn't a good timing for me. I was thinking postponing it after my traveling back to the states. But it was at the risk of my opportunity got taken by others. It was an easy interview, starting with some behavior questions, like why BlackRock, what does BlackRock do, why software engineer, etc. Then I was asked some questions about my resume, a project, and some experience. Then data structure, C++ and Java. Finally a coding problem.

    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeksinterviewed at BlackRock (San Francisco, CA) in November 2014.

    Interview

    The hiring process consisted of a phone screen followed by an on-site interview. The phone screen was straight forward and was mainly a resume review and some technical questions. No coding! The on-site interview was 4 hours - 4 interviews back to back in the SF office. The interviews were very different from the usual technical interviews. They focused more on skills than memory. One round was behavioral and one was anlytic, and the other two were technical.

    Interview Questions

    • Apart from the technical aspects, they also focus a lot on the behavioral and analytic questions.   1 Answer
