Crush technical interviews
Live help on coding challenges, system design, and deep technical questions — grounded in what's on your screen.
How MoJu helps
Technical interviews reward clear thinking under pressure. MoJu watches the problem on your screen, listens to the interviewer, and surfaces the approach, edge cases, time complexity, and space complexity so you can talk through the solution like an engineer, not a memorizer. Use it to prepare for coding interviews, system design interviews, LeetCode screens, and HackerRank assessments.
What you get
Coding problems
Approach, edge cases, time complexity, and space complexity for LeetCode and HackerRank questions.
System design
Structured components, data flows, trade-offs, and scaling considerations for system design interviews.
Screen-aware
MoJu reads the actual problem on your screen and answers about it.
Common questions
Does MoJu work on LeetCode and HackerRank?
Yes. MoJu works on LeetCode, HackerRank, CoderPad, and other coding platforms, and can read the problem directly from your screen.
Can it help with system design?
Yes — MoJu suggests components, data flows, trade-offs, and scaling strategies as the discussion unfolds.
Can MoJu help me prepare for a coding interview?
Yes. Use MoJu for mock practice and real-time guidance on coding, algorithms, data structures, and system design. It helps you explain your reasoning, edge cases, and complexity clearly.
