I don't understand AI yet. Can I still do this?
Yes. If you've used ChatGPT, you can start. Your mentor shows you which AI tools to use, and how, as you build.
Won't this eat into my DSA prep?
No. It's about 3–5 hours a week, and you plan them around your classes and prep. Build Theory runs alongside your DSA prep, not instead of it. Coding rounds still matter. This gives you something to talk about once you clear them.
Is it online or offline?
Fully online, so you can do it from anywhere, around your classes. The one exception is Demo Day: one in-person day in Hyderabad where you present what you built.
What happens after I apply?
Fill a short application. About 5 minutes, no payment. Prashanth calls you within 24 hours to talk through your idea and see if it's a fit. If it's a fit, you confirm your seat with ₹500. It's adjusted against the fee and non-refundable.
