Shopify Data Scientist interview questions

TL;DR avoid Shopify. There are a lot better companies out there. I should have read the Glassdoor feedback here before even starting the interview process. Yes, it was indeed a waste of time. I had to contact the recruiter multiple times to get feedback, otherwise they would have happily ignored me, after having interviewed, without telling me the interview outcome. Very, very unprofessional. Recruiter contacted me and chatted about about my background and why I was interested in Shopify. At the end of that conversation she was trying to get expected salary info from me, which I pointed out is an illegal question to ask in the State I live in. That was awkward, but I had to stand up for myself. I had then a 1h technical interview and then puff, nothing for a while. Disappeared. After some pings the recruiter bothers to get back to me with the template regret answer. Such an unprofessional way to manage relationship.
