Practick.io is a peer-to-peer mock interview platform that helps engineers prep for technical interviews with real practice, not just theory. Instead of paying for expensive mock interview services, users earn and spend credits by interviewing each other โ conduct a mock interview for someone else, earn a credit, then use that credit to book a mock interview of your own. It's built for candidates preparing for DSA, system design, and behavioral rounds who want realistic, structured practice from peers who've been through the same grind.
