Pramp

Pramp connects developers with peers to conduct free, real-time mock coding interviews via video. You take turns being interviewer and interviewee, practicing on genuine problem sets used at major tech companies. The peer-to-peer model means no cost and genuine pressure, since you're interacting with actual people. Pramp recently integrated with Exponent to expand its practice interview offerings.

Best for developers who learn well through authentic human interaction and realistic practice scenarios. Unlike platforms where you write code against test cases, Pramp recreates the exact social dynamics of a real interview, including explaining your thinking to a live interviewer.
