The problem

The way engineers prep for DSA
in India is fundamentally broken.

After coaching 1,572+ engineers, Pranjal identified the exact patterns that cause people to spend months preparing and still freeze in interviews. Here's what's actually happening:

The Old Way

How 90% of engineers are preparing — and why they keep failing

  • 4-hour YouTube marathons you forget within a week
  • Random LeetCode grinding with no idea what pattern you're building
  • Stuck for days on one concept with no one to ask
  • Memorising solutions — then blanking on new variations in interviews
  • Study hard for 2 weeks, stop for 3, restart, repeat forever
  • Generic courses not designed for working professionals
  • No visual summary — every revision means re-watching hours of content

The Prepflix Way

The modern system that gets engineers interview-ready in weeks

  • Visual infographic per topic — entire concept on one page, instant recall
  • Topic → Subtopic → Pattern — always know what you're building towards
  • Bi-weekly live group call with Pranjal — doubts cleared, progress reviewed (Mentorship plan)
  • Pattern-first teaching — solve any new problem, not just the ones you've seen
  • Built-in accountability — consistency baked into every week
  • Designed for 1.5–2 hrs/day around a full-time job
  • 5-min summary video per topic — revise before any interview in minutes
For every single topic

4 formats.
Zero gaps in understanding.

Every competitor gives you a problem list. We give you a complete learning system — four formats engineered to work together so you never need to open another tab to understand a concept.

Busy day? Open the infographic. Deep study? Watch the lecture. Interview tomorrow? 5-min summary video. One system for every situation.

01 — In-Depth Lecture

Full Video Lecture

Live coding, edge cases, common mistakes and real interview questions. Deep understanding you won't get from a problem list.

Core Learning
02 — Summary Video

5-Minute Recap

Every key concept from the topic compressed into 5 minutes. Watch on a busy evening, rewatch the night before your interview — forever.

Quick Revision
03 — Visual Infographic

Topic Infographic

All rules, edge cases, and patterns for one topic — on a single visual page. Builds instant recall without re-watching anything.

"I spent 8 months grinding LeetCode alone and couldn't crack a single round. Two months of Prepflix with Pranjal's weekly calls and pattern-based approach — I cracked Apple. The infographics alone changed how I revise. Nothing else comes close."

DSA + Mentorship plan

Not a TA. The founder.
Bi-weekly. Live. With your cohort.

Every other course gives you a teaching assistant. The Mentorship plan gives you bi-weekly live group calls with Pranjal Jain — IIT Kanpur alumnus and Ex-Microsoft engineer who has personally placed 1,572+ engineers.

Pranjal Jain — Founder Prepflix, IIT Kanpur, Ex-Microsoft

Founder & CEO, Prepflix

IIT Kanpur Ex-Microsoft

"The reason most engineers fail at DSA isn't intelligence. It's isolation and inconsistency. A regular group call — where you see peers struggling with the same things — changes everything. That's why I built it directly into the Mentorship plan."

Live Doubt Clearing

Stuck on a concept for days? Bring it to the call. Get it cleared in real time — stop losing momentum on things Pranjal can explain in 5 minutes.

Bi-weekly Progress Review

Every call starts with where the cohort is in the curriculum. Pranjal spots common sticking points, recalibrates pacing, and makes sure nobody drifts.

Consistency Accountability

The #1 thing students say made the difference: knowing a call is coming. It's the forcing function that makes everything else work — even with a full-time job.

Mock Interview Practice

As you near the end of the curriculum, calls shift to mock interviews — real FAANG interview pressure in a safe environment with direct feedback.

50-Seat Cohort — High Signal

Capped at 50 students so every question gets Pranjal's real attention. Small enough that your doubts get answered; large enough that you benefit from every question your peers ask.

Who this is for

Built for two people.
Engineered for both.

Working IT Professional

At TCS, Infosys, Wipro, or a mid-level company. You're done waiting for the yearly 10% hike. You want the 3–5× jump that product companies offer.

  • 1–8 years of service-based company experience
  • Can commit 1.5–2 hours/day around your current job
  • Tried LeetCode before but couldn't stay consistent
  • Targeting Google, Microsoft, Amazon, or funded startups
  • Need a concrete path, not just more content to consume

Fresher Targeting First Job

Final year or recently graduated. Your first offer is your first impression — make it from a company you're proud of, not just the first one that responded.

  • Final year student or 0–1 year of experience
  • Starting DSA from scratch or with basic knowledge
  • Want to compete with IIT/NIT graduates for the same roles
  • Targeting product-based companies for your first offer
  • Need structure and someone to answer your questions

Not for: People who want shortcuts, certificates without effort, or anyone not willing to code every day.

Pranjal Jain

Pranjal Jain is the Founder and CEO of Prepflix — India's most modern placement program for IT professionals making the service-to-product switch. A Computer Science graduate of IIT Kanpur and former engineer at Microsoft, he has personally coached over 1,572 engineers who have gone on to land offers at Google, Apple, Amazon, Microsoft, and Salesforce.

He built the 4-format DSA system after noticing the same failure pattern in every struggling student: they had content, but no visual summary for recall. They had motivation, but no weekly accountability. The program you see here is the answer — not just a course, but a complete modern learning system.

Questions

Everything you need to know
before you apply.

I only have 1.5–2 hours/day. Can I actually complete this?
Yes — this is exactly who the program is built for. The 4-format approach is designed for real life: deep-study the full lecture on weekends, do quick revision with the 5-min summary video and infographic on weekdays. Most students cover one topic per week on 1.5 hrs/day. The Core plan is fully self-paced. The Mentorship plan adds bi-weekly group calls if you want live accountability.
Striver and NeetCode are the best free problem lists in the world — we have enormous respect for them. But a problem list is not a learning system. Prepflix gives you a structured video lecture, a visual infographic, a 5-min summary video, and a detailed PDF — for every topic. The Mentorship plan adds bi-weekly live group calls with the founder. No list gives you that. If you've tried the sheets and couldn't stay consistent or get unstuck, this is what you've been missing.
Many of our 1,572+ placed engineers are from Tier 2 and Tier 3 colleges. Top product companies — Google, Microsoft, Amazon — hire on interview performance and problem-solving skills, not your college brand. This program gives you the structure and mentorship to compete with IIT graduates for the same roles. We've done it hundreds of times.
The patterns are language-agnostic. Pranjal uses Java in lectures, but everything applies equally to Python, C++, or JavaScript. Top companies accept any language in interviews. Use what you're comfortable with.
Pranjal Jain — the founder and IIT Kanpur alumnus — runs every call personally, not a TA. The bi-weekly group calls include live doubt clearing, progress review across the cohort, and mock interview sessions as you near the end of the curriculum. All calls are recorded so you can replay them anytime.
Yes. All lectures, 5-min summary videos, infographics, and PDFs are yours permanently — including any future updates to the curriculum. Revisit any topic at any time, before any interview, forever.
All lectures, summary videos, infographics, and PDFs are pre-recorded — so you study completely at your own pace, whenever suits you, and rewatch any topic as many times as you need. There are no fixed class timings. The Core plan is 100% self-paced. The Mentorship plan adds bi-weekly live group calls with Pranjal — recorded after each session so you never miss one. It's the flexibility of a recorded course with the consistency of a mentor who keeps the cohort on track.
The Core plan has no seat limit — it's fully self-paced. The Mentorship plan is capped at 50 students per cohort. This keeps the group calls high-signal: small enough that every question gets Pranjal's attention, large enough that the cohort energy is real. Once the 50 seats fill, the next cohort opens.
Mentorship cohort — 50 seats only
