Shopify Software Developer interview questions

Someone referred me and I got an email right away asking to schedule a 30min technical challenge. There were 2 other 1 hour challenges, one of which also included a 1 hour lifestory interview. All the interviewers were pleasant to work with and they all gave me hints with the challenges when I got stuck, helped google things, etc.

I still study in college and I apply for the intern postion of software developer. The interviewer is nice but I have to wait for my coop term to start.
