I applied online. I interviewed at Block (Toronto, ON) in Nov 2025
Interview
3 rounds of interviews, all oop, pretty simple lc easy/medium. Rejected for headcount.
Practice LC implementation, usually 2 followups. The main thing is to implement quickly and note limitations while doing so.
Firstly a resume screen and then a online assessment technical screen then an online call with around LeetCode medium type of problems with an interviewer on call walking through the process. Around an hour long with multiple parts if necessary
pretty standard; basic easy-medium leetcode style questions; 3 rounds of 45 minutes technicals; follow ups regarding time / space complexity but not too hard; standard lc prep should be enough
