I was sent a codility test. I think I had a countdown of 2,5 hours. Three different problems. I was not expecting to be asked specifically about SQL on that test, but the last problem was SQL.
Interview questions [1]
Question 1
- Pandas: data cleaning exercise
- Numpy: 2d array manipulation (rotations, etc)
- SQL: not easy if you haven't done those kind of exercises in sql before. Bus and passengers exercise.
