Spotify Data Scientist interview questions

-Use pandas to filter this dataset to only X rows and aggregate X metrics(pretty much same thing with SQL) -Look at A/B test results. Are these findings significant( which, by the way, this felt like a deliberate trick question, since they did not provide any numbers except the final results for the test and control cells, so no p value no confidence intervals ,etc. I tried to explain that you can't determine significance just by looking at two numbers side by side, but it felt like the interviewer kept trying to push me to say something statistically incorrect, because she then asked me if I would say the numbers are significant. Well, in the anxiety that I had from being in an interview, I thought maybe she meant she wanted me to use my best knowledge to guess if it was a statistically significant difference, which does happen in real life contexts when you don't actually have the means to run a proper test. However, since I did not move on to the next round, I believe maybe this was used as an excuse to say I was not statistically competent)

Python question on primes: Need to use if, elif etc. SQL - know AND, WHERE, HAVING etc. Graph analysis question
