FAQ

How many mock interviews should I do before my real interview?

Aim for at least 8-12 mock interviews spread over 3-4 weeks. This gives you enough reps to internalize patterns, reduce anxiety, and work through feedback between sessions. Most candidates see their biggest improvement between sessions three and seven.

Are AI mock interviews as effective as practicing with a human?

AI interviews are excellent for volume practice and instant feedback, but they cannot fully replicate the pressure of a live human interviewer. The best approach combines both — use AI tools like PracHub for daily reps and schedule human sessions through Interviewing.io for final polish.

Which tool is best for FAANG-specific interview prep?

PracHub is the strongest FAANG-focused option with company-specific question banks calibrated to real interview styles. For live human practice with actual FAANG engineers, Interviewing.io is the top choice. Use them together for comprehensive preparation.

Conclusion

The right interview prep tool depends on your budget and how you learn best. PracHub delivers the most comprehensive AI-driven FAANG prep at a reasonable monthly price. If you prefer human interaction, Interviewing.io pairs you with real engineers. For affordable volume practice, DevInterview.AI and Rubduck both deliver strong value.
