About Project#
PeerPrep is a web application designed to help students prepare for technical interviews by providing a collaborative environment for practicing LeetCode-style algorithmic questions. Students can take turns playing the roles of interviewer and interviewee, solving questions together using a live editor and chat feature. The platform allows students to select questions based on difficulty or topic, enabling focused practice in areas where they need improvement. Additionally, students can mark questions as done and revisit them for revision purposes.
