Interview

Two interviewers really stuck out to me. The first one was great! He was friendly, open, and engaging. The other was judgmental and somewhat conceited. Overall I had mixed feelings.

    Average Interview

    Application

    I applied through an employee referral. I interviewed at Uber (San Francisco, CA) in May 2018.

    Interview

    The process started by one of my LinkedIn connections referring me for the position. First I got a screen interview with the recruiter. She was nice and helpful. Then I was given a take home assignment and was given a week to complete it. It was a text-book machine learning assignment that you had to deal with missing values and perform modeling.
    This was followed by a coding interview, which went pretty well and the person who was interviewing me enjoyed my work. Then, I was told that I have to do another coding interview focusing on machine learning. The interview started with one of the challenging Leetcode examples. I didn't do my best there. Then I was asked some tricky questions about modeling and SQL. Next morning I received rejection email, which I was expecting.

    Pros of the interview:
    I learned through the process a lot. The first codepair was very good and I enjoyed it. Take home challenge also provided me with the real-world data and application of machine learning.

    Cons of the interview:
    -I felt there is a lack of coordination in Uber's process. For example, I was asked to have a codepair on machine learning concepts, which I prepared myself for, however, I was mainly asked software engineering questions and non-practical statistic concepts.

    -I felt UberATG R&D is a bit confused about the application of machine learning to this new area and it seems there is no real active project going on.

    In total, although the process was a good learning experience for the future of my job hunting experience. However, comparing to other companies that I have been applying to, lack of transparency, coordination, and direction in the hiring process of Uber could be frustrating and discouraging.

    Easy Interview

    Application

    I applied through an employee referral. The process took 4 weeks. I interviewed at Uber (San Francisco, CA) in March 2018.

    Interview

    Asked friend for a referral. Phone screen followed by a take home assignment, which went well. I was invited for onsite where I was interviewed by 5 people from the team.

    I thought the interview went well, the coding interview was a bit hit and miss because lack of familiarity with the interface. All the other team members told me it's not important for this team or the role. Most of the questions were open ended and vague, it felt like the interviewers liked my answers. A week later I was told I am not the right fit for the team.

    Application

    I applied online. I interviewed at Uber.

    Interview

    Brief chat with recruiter then a phone screen with a member of the data science team.

    The call with the team member started with a brief description of the position, as well as my background. After that we went into technical questions and I have to say, I don't think the interviewer had very much experience in the work world, especially not conducting technical interviews. Here's that part of the conversation went:

    Uber: That's the right answer, but I'm looking for one other point.
    Me: Could you provide some feedback or guidance so as to direct me towards what you're looking for?
    Uber: I'd like to hear how you'd work through the problem.
    Me: I just walked through my thought process, described why that was my thought process, and how I came to the answer. I don't know what else you're looking for, can you help me understand what I'm missing?
    Uber: Ok, let's move on.

    This happened multiple times. By the end of the call I was honestly really annoyed.

    Is this how the data science team works at Uber? No guidance or feedback???

    Average Interview

    Application

    I applied online. The process took 1+ week. I interviewed at Uber in January 2018.

    Interview

    Step 1: Brief chat with the recruiter.

    Step 2: A 1-hour technical interview with a data scientist. Mostly business case questions with a data science twist.

    Step 3: A coding assignment. They ask that you spend no more than 8 hours on it, but these things are always biased toward candidates who have the time to pour more hours into them and "wow" someone who will look over it for about 5-10 minutes.

    I handed in the coding assignment and waited around 4 days, when they got back saying they "decided not to move forward in the interviewing process."

    I asked for feedback and got none.

    I don't know how companies get away with doing this sort of thing. It's a red flag for me if they can't provide feedback after pouring 8 hours into an assignment they gave me.

    Interview Questions

    • They told me how one aspect of Uber's business worked years ago, and how I'd improve it. Mostly logistics based. The data science assignment was on predicting ETA given rider and driver data.   Answer Question
