    Average Interview

    Application

    I applied through an employee referral. The process took 3 weeks. I interviewed at Grab (Seattle, WA).

    Interview

    Stay away from this company!!!!
    I was referred by one of their former employee. HR reached out me, and had a short conversation. A week later, I was told there was not data scientist opening (Then why the HR set up a call with me and waist my time?!).
    Then I moved on and interviewed their competitor and got an offer in another city. Then I reached out HR again, and he set up interview for me immediately.
    I interviewed and got an offer. They gave me a low ball oral offer, but told me if I can present a competing offer, they are willing to match to their best. The reality was, they did not increase offer at all!!!!!
    HR kept saying, I have to accept offer first, then they conduct background search, then they will send written offer (What the!) .
    I took the offer and reject my other offers.
    And then, HR called me, told me they decide not to move forward! What the!

    Easy Interview

    Application

    I applied online. I interviewed at Grab.

    Interview

    First interview (Skype): HR discussion. Very typical.
    Second interview (Skype): Casual discussion on various ML techniques, without covering anything particularly in depth. Quite elementary questions, I guess, basically to check if the candidate has prior ecperience with data science or ML

    Data Scientist Interview

    Negative Experience
    Difficult Interview

    Application

    I applied online. I interviewed at Grab (Singapore (Singapore)).

    Interview

    I had an interview with an HR employee. She was very professional, and the discussion was enjoyable sharing my experience and knowing more about the role etc. Then They sent me two codility tests saying it's about data science.
    The first test was merely algorithms implementation, zero data science. FYI, many data scientists they come from Finance, Business, Maths and Physics backgrounds and they DO NOT need to code binary trees and dynamic programming to be successful as Data Scientists. Anyway, I have never used Codility before, and I was surprised that during the test Codility said your program is correct, but when submitting, it added some other tests making my program not correct anymore. I even tested on my local machine and I don't know what they are expecting.
    The second test was stolen from Udacity, the famous Bay Area Bike Sharing challenge, they give you 6 hours to do the whole AWESOME process, from EDA to prediction using many algorithms etc. The challenge was enjoyable to do but I guess working 6 hours without a simple breath and you don't know if you should add more EDA or not wasn't pleasant at all.
    Being frustrated about the first test, I just did the second on my own time and I didn't really care about finishing it, I was doing more freestyle more than following the rules.

    Interview

    Reached out to HR and got an email back relatively fast, but next steps were not clear. Eventually met someone from the team, and had a short interview that was half technical, and half about resume/previous experiences.
