Business Value of the APP
Hello,
Thank you for your incredible effort in this course and for providing such helpful content. I have a few doubts regarding the development of an interview preparation app:
Motivation & Uniqueness
What would drive me to develop an app like this?
What makes it stand out compared to using ChatGPT directly?
Added Value Over ChatGPT’s Default UI
Currently, I can simply go to ChatGPT and prompt:
“I have an interview at Amazon. Please give me 5 interview questions based on my experience.”
And it would generate relevant questions.
So, what additional value does a dedicated app provide?
Core Differentiation
Is the key advantage simply having a predefined database of company-specific questions that the model selects from?
Or are there other unique aspects that make the app more effective than a general-purpose AI chat interface?
I hope my point is clear. I’d appreciate your insights on how such an app could offer a significantly better experience than just using ChatGPT.

Hi Ahmed,
Thank you so much for your thoughtful message and kind words about the course!
I'm really glad you're finding it helpful. Your questions are spot-on, and I’m happy to clarify them.
The core motivation for developing this kind of app is to learn how to build real-world LLM applications using tools like Streamlit and OpenAI’s API, while also creating a project you can proudly showcase in your portfolio. This hands-on experience gives you practical exposure to prompt engineering, user interaction design, validation, evaluation logic and more.
Once you’ve built the base version it’s easy to extend it with new features or adapt it for other use cases such as a language-learning tutor, resume reviewer or customer support assistant. Or, if you’re feeling ambitious, you could even build a multi-functional agent that handles multiple job preparation tools in a single, seamless experience.
And “Why not just use ChatGPT?” Great question. While ChatGPT can generate interview questions, this app offers control, customization, and structure.
With your own app, you can:
- Tailor it to specific industries and companies with your own question database
- Create a structured interview flow with stages like setup, questioning, and evaluation
- Offer a focused interface, unlike ChatGPT’s general-purpose UI
With this app we build on top of ChatGPT to create a more domain specific, and extensible experience that is going to look great on your resume.
Here are a few key advantages:
- Company-specific content - based on real-world interviews
- Controlled interview flow - with follow-ups, timed answers, and remarks
- Custom evaluation - based on real hiring criteria, not vague LLM feedback
And if you manage to discover new ways to overcome ChatGPT’s limitations in interview simulations, you’re not just building a great project—you’re exploring a real business opportunity.
Thanks again for your question! If you have any more concerns or questins, feel free to reach out.
Happy learning!
