I applied through a recruiter. The process took 1 week. I interviewed at Shopify (Ottawa, ON) in Mar 2016
Interview
Informal, 20 minutes. The interviewer was inside the Data Group, he was nice and tried to make me comfortable, with questions about what I like about data. He explained the kind of work they do and he told me pro and cons that working on dirty data implies. He asked about my programming skills and my interest in data analysis and data manipulation. But the conversation was not so technical, we mentioned Python and a couple of libraries.
