      Senior Data Engineer Interview

      17 Dec 2019
      Anonymous interview candidate
      No offer
      Positive experience
      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at QuantumBlack in Dec 2019

      Interview

      One of the recruiter messaged me from Linkedin for an opportunity in London but I'm based in SEA so he directs me to SEA office which is very convenient! The recruiter who handled me was very polite and professional. The entire process was fast and smooth. Response and feedback from recruiter and interviewer were really fast. It took about 3 weeks for overall stages I've been through. First stage : The recruiter will introduce the company and their products. Then they will ask some general introduction questions about yourself. Second stage: Technical test using HackerRank. Be sure to familiarise with HackerRank UI. The test is 2 hours where 3 SQL questions and 2 Python questions. Easy to intermediate level but I find 2 hours are still quite challenging. Third stage: Live coding interview for 2 hours with one of the data engineer ( I think he is Head of Data Engineer in the region). It was my first time doing live coding but he made me feel comfortable, allow me ask questions and he interrupts me time to time but not bad at all. He started with introduction from both side. Then, 1 hour +- for live coding based on case study. The questions are not hard but it is nerve-wrecking to do live. He was willing to share feedback from how I did and what I can improve technically and my communication skills. How they handle their recruiting process makes me comfortable and even though I didn't get the job. I'm satisfied with my achievement and how I was treated was very welcoming.
