Why engineers trust it
Not another PDF of copy-pasted questions
Written by a working frontend engineer
Built by someone who codes and sits on interview panels for a living. Every answer is what actually gets said in the room, not a textbook summary.
Questions from real product-company rounds
Collected from interviews at Razorpay, Swiggy, CRED, Zepto and similar companies, then grouped by the round they appear in.
A structure built to be remembered
Every question has a one-line answer, the detail, the code, why interviewers ask it, and the follow-up they reach for next.
Used by thousands of developers
From freshers clearing their first round to seniors switching for 10+ LPA. The testimonials below are theirs.

Devs who cracked it
Real feedback from developers who used ForgeFrontend kits
“I bought the Complete Bundle and prepped JS, React and frontend system design from one place, no juggling ten tabs. Cleared PhonePe in four rounds straight.”

Frontend Engineer · Joined PhonePe
“The Career & Negotiation guide paid for itself a hundred times over. I used the exact scripts to take my offer from ₹16 to ₹23 LPA.”

“The React Q&A and machine coding handbooks are the most interview-relevant prep I've found. Walked into Swiggy's rounds genuinely confident.”

Still confused?
Pick the Complete Frontend Kit.
It can't be the wrong choice.
Frontend interviews don't stay in one lane. A React role still opens with JavaScript, a senior round adds system design, and every offer ends in a negotiation. The Complete kit covers every one of those rounds, so nothing you get asked is a surprise.
- Both kits inside: the full JavaScript and React kits, every PDF
- Plus HTML/CSS, TypeScript, frontend system design and the career & negotiation guide
- 13 PDFs, readable online, one Drive folder, one zip
- ₹499 for everything, ₹199 less than buying JS and React separately (₹698)
