As answered by people managing Olvy and DevPrep.app.
DevPrep.app's answer:
Software developers and DevOps engineers who are preparing for technical interviews.
DevPrep.app's answer:
DevPrep.app offers a genuine two-way voice conversation for interview practice. The AI asks questions out loud, evaluates your spoken response, gives feedback, and asks follow-up questions just like a real technical interviewer would. Most tools make you type. Real interviews make you talk. DevPrep.app also includes 500+ flashcards across 15 topics with progress tracking and review mode, all working in your browser with no app install needed.
DevPrep.app's answer:
Most interview prep tools train you to write answers, not speak them. DevPrep.app trains the skill that actually matters in interviews — communicating clearly under pressure. It works in your browser with no app install, supports both desktop and mobile voice interviews, and includes 500+ flashcards with progress tracking across 15 topics.
DevPrep.app's answer:
Built by a developer who noticed that knowing the answers and being able to say them confidently out loud are completely different skills. Most prep tools only train one of them. DevPrep.app was built to train both.
DevPrep.app's answer:
ASP.NET Core 7, React, TypeScript, Azure OpenAI (GPT-4o), Azure Cognitive Services Speech SDK, Web Speech API, Azure Container Apps, Azure Static Web Apps, Stripe, SQL Server
