First-hand accounts from people who interviewed at Robinhood.
Data Scientist
Started with a phone call from a recruiter. If that went well, I had a virtual technical screen. If I passed the technical screen, I had a virtual onsite interview. The product sense and SQL parts were pretty easy. The stats question was a bit tough, though. Unfortunately, it felt like the interviewer wasn't really engaged, maybe they'd already decided. Also, the interviewer's accent was really thick and hard to understand, which made the whole thing a bad experience.
- Tell me about product sense.
- How would you approach this SQL problem?
- Can you answer this statistics question?
Data Scientist
Robinhood's interview process feels professional but also welcoming. For me, it was 3 rounds. The first round was a screening interview. It was supposed to be a phone call, but since I live nearby, I got to do it on-site for about 30 minutes. We discussed my background in research and data science. The second round was an on-site interview with four 45-minute sessions: an open-ended data science session, a white-board programming task, an on-computer programming task, and another open-ended data science session. The third round involved meeting with a co-founder to discuss the company's mission. Overall, the interview experience was a great opportunity for me to tackle interesting problems and see the company's passion.
- What makes an investor 'good' in your view, and what methods would you use to find them?
- Could you explain churn and how we might forecast a customer's likelihood to churn?
- Imagine you have an array of numbers indicating the heights of 2-d mountains; calculate the water that would be trapped after it rains.
Data Scientist
They asked me to book a time to get a 48-hour data science challenge. It covered basic probability and ML, plus a case study to predict churn from given data. I'm pretty sure I nailed the first three questions. For the case study, I found all the required metrics and even did an extra analysis that wasn't asked for. After that, I had to chase the recruiters, and eventually, they told me I 'wasn't a good fit.' Since I thought I did really well, I asked for feedback to understand what went wrong. They said the company has a 'no-feedback' policy, so they couldn't share anything. A total waste of a day, and I don't even know why I was rejected. While they didn't ghost me, it was like getting zero learning experience.
- Could you predict user churn based on the provided case study?
