Technical Mock Interview Practice
Prepare for coding rounds, system design discussions, and technical deep-dives with an AI interviewer that adapts questions to your stack and experience level.
Start Technical Interview →What Technical Topics Are Covered
Data Structures & Algorithms
Arrays, linked lists, trees, graphs, hash maps, dynamic programming, sorting, and searching. Questions range from easy warm-ups to hard optimization problems.
System Design
Design scalable systems, choose between SQL and NoSQL, discuss caching strategies, load balancing, and microservices architecture. Tailored to your seniority level.
Language & Framework Specifics
Questions about your declared stack — Java concurrency, Python data pipelines, React state management, Node.js event loops, Kotlin coroutines, and more.
Problem-Solving & Trade-offs
Real-world scenarios: optimizing a slow database query, choosing between consistency and availability, designing an API contract, or debugging a production issue.
How Technical Interviews Are Scored
Each answer is evaluated on:
- Correctness — Is the approach/solution technically sound?
- Completeness — Did you address edge cases and constraints?
- Communication — Did you explain your thought process clearly?
- Optimization awareness — Did you consider time/space complexity?
After each answer, you receive a score (0–100), specific feedback, and a model answer showing what a strong response looks like.
Preparation Tips for Technical Interviews
- Think out loud — interviewers assess your reasoning process, not just the final answer.
- Clarify constraints before solving — ask about input size, edge cases, and expected output.
- Start with a brute-force approach, then optimize. Show you can iterate.
- Practice under time pressure — real interviews have 20–45 minute windows per problem.
- Review fundamentals: Big-O notation, common data structure operations, and basic SQL.
