Frequently Asked Questions
Is AI feedback as good as human feedback?
For behavioral interviews, AI feedback trained on real hiring patterns can catch the same issues human coaches identify: unclear structure, missing specifics, weak conclusions. The advantage is availability and consistency - you can practice 20 times in an hour with AI, versus once per expensive human session.
Can I use multiple platforms together?
Absolutely. Many successful candidates use Revarta for daily behavioral practice and combine it with other tools for specific needs (coding practice, system design study, etc.).
What about free options?
Pramp offers free peer practice, and Revarta offers a free trial. For sustained practice, even budget-friendly paid options often provide better ROI than extended job searches caused by poor interview performance.
How much should I practice?
Research suggests that consistent daily practice (even 15-30 minutes) produces better results than cramming. The key is speaking your answers out loud, not just thinking them through.
