I applied through other source. The process took 3 days. I interviewed at BlackRock (New York, NY) in October 2017.

Interview

Abrupt, straight to the point, brief self intro then straight to technical questions, didnt even get to ask about the company. I was not warned about the experience I had so I was taken by surprise.

    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.

    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.

    Tough super day. Some technical questions, some non-technical brain teasers. Four total interviewers that lasted about an hour each. There was no financial questions because they didn't expect any software knowledge coming in as an intern.
