Optiver Data Science interview questions

Coding test on Hackerank including three coding tests and some probability model questions and one designing question. The coding part is about using python (pandas and numpy) . The probability part includes gambler ruins etc. The wording of the questions are confusing. And they give you two hours to do it. Make sure your brush off your pandas and numpy knowledge before doing it.

First a HackerRank and then phone interview to get the on-site interview. On-site consisted of four parts: behavioral interview, two technical/critical thinking interviews, and a conversational interview with a senior data scientist. Overall, the experience was great. They handled all the logistics seamlessly.
