I applied through an employee referral. The process took 2 days. I interviewed at Shopify (Montreal, QC) in Dec 2015
Interview
The process takes about four different steps. The first two steps are just to check how do you behave and during the other two they evaluate your technical skills. They are very nice and what they ask is what you should expect for an interview.
Interview questions [1]
Question 1
The third step of the interview consisted of a classification problem. The point was to solve the problem in collaboration with the interviewer. To be more specific, the problem was a multi-class classification problem where the data consisted of product descriptions and the algorithm to use was TFIDF.
