Levelop is an AI-powered interview preparation platform designed for software engineers aiming for roles at companies like Google, Amazon, and Meta. It combines coding and system design practice into a structured, guided experience with real-time feedback and progress tracking.
Built for the Indian market, Levelop offers pricing in INR and includes a free first sprint with no payment required.
The Problem
Most interview prep today is unstructured: Random problem solving with no clear progression Limited feedback beyond “wrong answer” No visibility into actual weak areas System design learning that lacks depth and practice
This often leads to inconsistent progress and repeated mistakes.
How Levelop Solves It
AI-Powered Mentorship Aurora (System Design Mentor) Guides users through concepts, architecture decisions, and interactive learning before allowing hands-on design. Orion (Coding Mentor) Activates when a user submits incorrect code. Diagnoses gaps in understanding and guides users through targeted exercises until the concept is clear.
Failure-Driven Learning Instead of passive hints, Levelop uses incorrect attempts as signals to trigger structured learning flows, ensuring users fix root causes rather than memorizing solutions.
Integrated Learning Flow Coding and system design are combined into a single workflow Users move through guided sprints instead of random problem selection
Progress Tracking Sprint-based structure with clear visibility into progress Identifies strengths, weaknesses, and areas for improvement
Ideal for: Software engineers (0–5 years experience) Candidates preparing for technical interviews at top product companies Developers looking for structured, feedback-driven learning

- Technical skills: have they got the walk to match the talk? Programming languages on a resume mean little if candidates are unable to demonstrate their hard coding skills. You can test these skills with technical skill tests, such as the ones created by Codility or HackerRank. - Source: dev.to / over 2 years ago
