Interview

I interviewed at Blackrock in Nov 2016. The process is extremely badly designed, they think they are google and thus they take 6-8 interviews, 1st 4 are some junior analyst level interviewers who are just there to get interview experience and thus waste our time, then come the hiring managers who have no idea how to select candidates in their team and in the end they let most of the candidates go with little or no reason. I would reccomend if you have other offers, make sure Blackrock is the last one.

    Application

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

    Interview

    Chaotic! HR does not know what they are doing and are disorganized. Full of miscommunication and last minute cancellations & rescheduling. They even kept wavering with the interview decision communications. Very unprofessional on the scheduling and logistics part. Interviews are normal. Mostly leetcode medium and easy difficulty questions and some OOPS trivia questions.

    Application

    I applied online. The process took 4 weeks. I interviewed at BlackRock in February 2017.

    Interview

    completed their hacker rank challenge. And I was invited onsite. before the onsite, I asked in an email about the interview process and was told the morning sessions would be technical. It turned out to be more than 7 rounds of interviews through out the day. At some point, I asked my interviewer in the afternoon, "how many more rounds?" because at some point, you are just very tired mentally. But seemed like my interviewer had no idea and told me to wait in the room and see if anyone else will come in.
    And you would think .... after 7 rounds of interviews, if they were not interested in you, they would either email or call. But non of that happened. Last time I interviewed was 2014, maybe 2017 is one of those year where companies like Blackrock doesn't bother to talk to candidates that they don't want anymore?
    It's just very unfortunate. They will give you an info session about the company and say that their CEO/leadership feel everyone should know a little about finance or the business. During my 7 rounds of interview, no interviewer even spent 1 minute talking about the business.

    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.

    Interview

    Applied online and then given a hirevue coding test + video interview question. The coding test was pretty standard java string questions and the hirevue video interview just asked why you majored in what you major. I do not know what comes next as thats all I got to. I assume the next step would be an onsite or phone interview.

    Application

    I applied online. The process took 2+ months. I interviewed at BlackRock (New York, NY) in September 2016.

    Interview

    These is the description of video record and coding challenge. For video record, only one simplest behavior question. The coding challenge is a progressive problem, from simple string input process to finally sort string array.

    Interview Questions

    • For coding challenge, first they give you one string, using some special character to separate different stocks, and ask you to standardize them. Then the question become more and more difficult, like select the most profitable stock but each question can use the method in previous questions.   Answer Question

    Application

    I applied online. The process took 1+ week. I interviewed at BlackRock (New York, NY) in September 2016.

    Interview

    Received an offer for the internship last year, but declined it. Returned to apply online to the full time position (was not reached out to by HR). First step is an online coding project/challenge, pretty extensive (takes several hours). Very disappointed to be told that there were no more spots for the year. Disrespect of my time. HR should take down out of date postings, especially ones that require such a time commitment to apply to.

    Interview Questions

    • coding project, as mentioned above.   1 Answer
