Average Positive Toronto, ON

My first steps were pretty structured: I had an HR screening and then a 1:1 with the hiring manager focused on growth analytics. After that, I was pulled into a take-home case.

What stood out was that the take-home wasn’t just about writing code or getting something to run—it was evaluated for presentation. I eventually got to the point where my work was meant to be presented, but I didn’t make it to the presentation stage, so the process stopped there.
