Preps

Preps is an AI-powered platform designed to revolutionize how software engineers and developers prepare for technical interviews. Its core value proposition lies in moving away from the passive, solitary practice of solving algorithmic problems on static platforms, towards an interactive, asynchronous simulation of a real interview environment. The tool provides a dynamic space where users can articulate their problem-solving process out loud, receive AI-generated feedback on both their technical approach and communication skills, and iteratively improve their performance, thereby building genuine confidence and competence.

Key features: The platform allows users to record themselves solving algorithmic challenges while explaining their thought process, mimicking the 'think aloud' expectation of live interviews. The AI then analyzes these recordings, offering specific critiques on code efficiency, logical errors, and clarity of explanation. It provides a library of curated problems categorized by difficulty and company, and generates personalized study plans based on performance gaps. For example, after a mock interview on a graph traversal problem, the AI might highlight a missed edge case in the BFS implementation or suggest a more optimal data structure.

What sets Preps apart is its focus on the *communication* aspect of technical interviews, which is often neglected by traditional coding practice sites like LeetCode. While competitors focus on code correctness and runtime, Preps' AI evaluates soft skills such as how clearly a candidate structures their verbal explanation, manages ambiguity, and collaborates with a hypothetical interviewer. The platform is technically built to process natural language and code execution traces, providing a holistic assessment. It operates as a web application with a simple, distraction-free interface, requiring no complex integrations.

Ideal for computer science students, bootcamp graduates, and experienced software engineers actively seeking new roles at technology companies. It is particularly valuable for candidates targeting major tech firms (FAANG, etc.) where the behavioral and system design components of interviews are crucial. Use cases include last-minute interview cramming, systematic multi-week preparation sprints, and practicing for specific companies known for their unique interview styles. The tool serves the broader information technology and IT consulting sectors where technical screening is a standard hiring gate.

As a free tool, Preps offers its core asynchronous interview practice and AI feedback without cost. This makes it an accessible entry point for all users, though advanced features or expanded problem libraries may be considerations for future premium tiers.
