Shopify Senior Data Scientist interview questions

Multiple rounds of interview: 1)python pair programming : object oriented programming, unit testing, debugging 2)SQL programming 3) HR chat your background, why you like data science, 4) past projects: your experience, your methods, results, lessons

First step was the recruiter interview with generalities about my experience and current role to see the fit. Second step was a pair code interview with a native Python problem. About the code interview, I didn't have a good experience mainly due to the initial solution presented wasn't in a production standard pattern and difficult to read. I was expecting a more applied solution and interesting problem.
