Positive Experience
Difficult Interview

Application

I applied online. The process took 2+ months. I interviewed at BlackRock (New York, NY) in January 2017.

Interview

Nicely designed, 4 back-to-back interviews, mixed behavior and technical questions. You should prepare a lot for Java concept questions such as the difference between Concurrent HashMap and synchronized HashMap and perhaps low-level knowledge.
Asked about your background related to finance, why BlackRock? What do you want to get from BlackRock? Things like these.

    Difficult Interview

    Application

    I applied online. I interviewed at BlackRock (New York, NY) in June 2016.

    Interview

    I applied through LinkedIn and received an email from Manager after one month. First round was hacker rank test. This test many topics like JavaScript, Java, HTML, CSS, Threads in Java and UML Class diagrams. We also have to upload our any previous written code for any assignment or project. After some days, got the positive feedback from the Manager and asked to schedule 5 video interviews. 4 out of these 5 interviews were technical. They covered topics from core java, design questions, Dynamic programming, threads, Algorithms, Spring and technologies mentioned in my resume. Last video interview was with HR and we discussed about the BlackRock business model and the position roles and responsibilities.
    After this I called onsite for another two rounds. First round was technical and second round was both technical and HR type questions.
    After this I was called to set up one more video interview.

    1 short on-campus technical interview lasted about 30 minutes (interviewer came late). Called back for superday about a week later.

    Difficult Interview

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at BlackRock (New York, NY) in October 2014.

    Interview

    I have one-round in-campus interview first. And then I got an email to be onsite. There are four rounds interview onsite. In the first round, it seems that he is interested in my project. He asked me to design a recommending system for room booking. We discussed about the features of a room and how to use this feature to recommend room for the user. The second round is about the technical quetions. He asked me about the multi-thread and lock questions in Java. Actually I am not familiar with Java multi-thread so I am feeling not good in this round. In the third round, he asked me if I am good at multithread and I said no. He keeps asking knowledge questions instead of algorithm questions. In the fourth round, he asked me so SQL queries but they are quite easy.

    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed 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
