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
I applied online. The process took 3 weeks. I interviewed at Block (New York, NY) in Apr 2025
Interview
There were 3 pair interviews with engineers from Block. Each round was pretty much the same difficulty, I think they were more focused on how you communicated about what you wrote along with a correct implementation.
