FAQ
Q: Is it allowed to use AI tools during coding interviews?
It varies by company. As of 2026, Meta explicitly allows AI tools in their AI-enabled coding interview format. Most other companies prohibit external assistance. Always check the specific company's policy before your interview.
Q: What's the difference between LeetCode-focused tools and general interview tools?
LeetCode-focused tools (Leetcode Wizard, Interview Solver) are trained specifically on algorithmic problems and perform well on OA-style assessments. General tools (Final Round AI, LockedIn AI, InterviewCodeAssist) cover a broader range including behavioral and system design questions, which are required for complete interview loops at most tech companies.
