I tried Revarta for an interview I had coming up because it's hard to practice by yourself and mock interviews are cumbersome to schedule and feedback can be inconsistent. I was blown away by Revarta's quality questions and the detailed feedback (along with suggested improvements). Revarta was accurate on what questions were asked and the feedback I received from the interview team. I will definitely incorporate Revarta as part of a consistent practice since it improves my answers and I can do it whenever I have the time, for as much time as I need (with no subscription!)
Revarta strikes the perfect balance between flexibility and structure. I love that I can either practice full interview sessions or focus on specific questions from the question bank to improve on particular areas - this lets me go at my own pace The AI-generated feedback is incredibly valuable. It's helped me think about framing my answers more effectively and communicating at the right level of abstraction. It's like having an experienced interviewer analyzing my responses every time. The interface is well-designed and intuitive, making the whole experience smooth and easy to navigate. I highly recommend Revarta, especially if you find it challenging to do mock interviews with real people due to scheduling conflicts, cost considerations, or simply feeling shy about practicing with others. It's an excellent tool that delivers real value.
Practice at any time of day. No need to schedule with someone.
Stay worry free from someone's judgment. No one is watching you.
Practice as much as you want until you're confident. Practice speaking out loud, privately, without the cringe.
Rome wasn't built in a day, so repeat until you're confident. You can become unstoppable.
