Competitive programming & technical interview prep at UVic.
01 About
A room for people who like hard problems.
UVic CPC is for students training for programming contests, building sharper algorithmic instincts, or preparing for technical interviews. We learn the patterns, then put them under pressure.
Think in teams
Share whiteboards, compare approaches, and learn how a contest team actually works.
Start where you are
Basic programming is enough. Curiosity and consistency do the rest.
02 Meetings
Open to every UVic student with basic programming experience.
Twice a week.
One shared scoreboard.
Bring a laptop. Show up for the first problem. Stay for the postmortem.
