Interview questions [1]
Question 1
How I would use RAG given I have an expert to work with.
I applied online. The process took 4 weeks. I interviewed at JPMorganChase in Jul 2025
Interview
Got the first interview call around 10 days after applying. First call is the basic introductory call including 5 basic questions on Python and Statistics, second call is with senior data scientist or with VP. If call with VP, questions tend to be more focused on behavioral rather than completely technical. If with senior data scientist questions asked would almost certainly be just technical. Expect statistical (bayesian and frequentist), coding(depending upon resume) and resume walkthroughs with in-depth explanations to actions taken during past work experiences. You need to get 90% of the questions correct if you want to proceed to the next step - Call with VP.
