No analysis of Prep Sarthi yet.

Overall verdict

  • DevPrep.app appears to be a niche coding/technical interview preparation tool, but I don't have verified, up-to-date information confirming its current quality, content accuracy, or user satisfaction, so I can't give a confident endorsement.

Why this product is good

  • Positioned as a focused resource for developers preparing for technical interviews
  • May offer structured practice problems or study plans
  • Likely targets a specific pain point (interview prep) rather than being a general-purpose tool
  • Web-based apps like this often have low barriers to trying them out

Recommended for

  • Software engineers preparing for coding interviews
  • Job seekers wanting a structured practice routine
  • Developers looking for a lightweight, focused prep tool rather than a full bootcamp
  • Users who prefer trying a specific niche tool before committing to larger platforms

Questions & Answers

As answered by people managing Prep Sarthi and DevPrep.app.

How would you describe the primary audience of your product?

Prep Sarthi's answer

Indian graduates and early-career candidates preparing for the large service companies, where the panel interviews your resume and the round is short. It also suits anyone who has written a strong CV but has never said it out loud.

DevPrep.app's answer:

Software developers and DevOps engineers who are preparing for technical interviews.

What makes your product unique?

Prep Sarthi's answer

It interviews you from your own CV rather than from a question bank. It reads the resume you upload and asks about the projects on it, so the questions are the ones only you can be asked, and it asks again when an answer is thin. The report is measured rather than guessed: the pause before you started speaking, your words per minute and your filler words all come from your microphone.

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.

Why should a person choose your product over its competitors?

Prep Sarthi's answer

Most tools cap how much you can practise, because a spoken interview costs them money every minute. Prep Sarthi runs on your own free Google Gemini key, so a pass buys unlimited practice instead of a set number of sessions. It also interviews in Hindi and Hinglish, which matters in India, where interviewers often switch language mid-question. And you can try it for twenty minutes without an account or a card.

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.

What's the story behind your product?

Prep Sarthi's answer

It came out of Interview Sarthi, a Windows app that helps during a live online interview. People kept asking for something to use before the interview rather than during it, and that is a different product, so it was built as one. It is made by one person in Delhi.

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.

Which are the primary technologies used for building your product?

Prep Sarthi's answer

Google Gemini Live for the spoken interview, over a WebSocket, with the microphone captured and resampled in the browser through an AudioWorklet. The site is static and the back end is a Cloudflare Worker with a D1 database. Your CV is read in your own browser and goes only to Google, on your own key.

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
