I applied online. The process took 2 weeks. I interviewed at Loblaw Digital (Toronto, ON) in Aug 2020
Interview
Asked questions about statistics and probability. Once you pass that interview they send you transaction data and you have to make a recommender system. (the feedback I got on the recommender was that they were looking for something more simple - less compute time)
Interview questions [1]
Question 1
lots of probability questions but they were not too hard
