    Data Analyst, Data Warehouse Interview

    Anonymous Interview Candidate in New York, NY (US)
    No Offer
    Negative Experience
    Difficult Interview

    Application

    The process took 2+ weeks. I interviewed at Quantcast (New York, NY (US)).

    Interview

    Received phone call technical interview invitation.

    First round : Consists of SQL, Coding problem and/or Shell scripting !

    First of all, why does a data Analyst position have coding problem ? Like now shall we data Analysts also solve LeetCode like software engineers ?
    We are pursuing Data Analysis !!!!
    Why make us solve LeetCode type coding problem in technical round ?

    Instead, ask Data related business or technical questions !!!

    If we would have solved LeetCode for coding problem, we would have just applied for SOFTWARE ENGINEERING.

    This company and the hiring team has no sense and do not know the difference betweeen SOFTWARE ENGINEERING and Data Analysis.

    DO NOT PUT CODING PROBLEMS !!!

    Difficult Interview

    Application

    I applied online. The process took 4 weeks. I interviewed at Quantcast (San Francisco, CA (US)) in February 2020.

    Interview

    The process was pretty standard. 1 phone call to explain the process, 1 coderpad and then onsite which had 4 rounds. Heavily inspired by Amazon SDE interview. Everyone from HR to employees who took the interview were really nice. Treated with lot of respect and but all of them were very curious on why I was leaving my old firm.

    Easy Interview

    Application

    I applied online. I interviewed at Quantcast in January 2020.

    Interview

    Applied through online. I initially got a phone interview (15-20 mins). The interview was simple. They just asked about myself and my experience. They immediately forwarded my application forward. The next round was a technical phone interview (60 mins). The interview went well. I discussed many algorithms with him. However, the interviewer was expecting one specific solution from me which was to get a solution through recursion. Got a reject the next day.

    The interviewer agrees with you all the time. That doesn't mean that the interview is going well. We can't say what is going on in the interviewer's mind.

    • You are tasked with building a service to find number of times we have bid with same value in a list of prev bids. Your service will be invoked several millions of times in a day and solution needs to be as fast as possible. Let us define api interface as "int countInHistory(int currentBid, int[] previousBids)".

      E.g
      prev bids - [4, 4, 4, 6, 6, 7, 9, 14, 14, 14, 14, 17]
      cur bid - 14
      ans - 4
      basically, is asked me finding how many counts in the array by less than log(n)   Answer Question
