4-hour YouTube videos are dead. Every topic comes with a visual infographic, 5-min summary video, detailed PDF, and an in-depth lecture — all recorded, yours forever, study at your own pace. Want live accountability? Add bi-weekly group calls with Pranjal in the Mentorship plan.
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:
How 90% of engineers are preparing — and why they keep failing
The modern system that gets engineers interview-ready in weeks
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.
Live coding, edge cases, common mistakes and real interview questions. Deep understanding you won't get from a problem list.
Core LearningEvery key concept from the topic compressed into 5 minutes. Watch on a busy evening, rewatch the night before your interview — forever.
Quick RevisionAll rules, edge cases, and patterns for one topic — on a single visual page. Builds instant recall without re-watching anything.
Instant RecallStructured theory, patterns, and solved examples in one place. The deep-dive resource when you want to read, not watch.
Deep Reference
Every topic follows the same proven structure. Your brain builds a reusable system — not a bag of disconnected solutions.

Recursion tree, memoization, subsets, N-Queens
XOR tricks, masking, counting bits, power of 2
DFS/BFS, LCA, diameter, serialization, BST
Top-K, K-way merge, sliding window max
BFS/DFS, Dijkstra, cycle detection, Union-Find
1D/2D DP, LCS, knapsack, interval DP
Fixed/variable window, string patterns, subarrays
Insert/search/prefix, XOR max, word search
Activity selection, interval scheduling, jump game
Mixed interview problems, complexity analysis, live mocks
Engineers from TCS, Infosys, and Wipro earning ₹6–12 LPA have gone on to land roles at ₹25–60 LPA. Here are three of them.
"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."
"The roadmap is what I was missing for 2 years. When you know exactly which pattern to apply and WHY — not just the solution — everything clicks. The group calls with Pranjal are worth the entire Mentorship plan. He doesn't just answer questions; he fixes your thinking."
"I work 9 hours a day. I had no confidence I could crack product company interviews. The structured path, 5-min summary videos, and Pranjal's weekly feedback changed everything. Cracked Microsoft in 4 months — while working full-time."
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.
Founder & CEO, Prepflix
"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."
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.
Every call starts with where the cohort is in the curriculum. Pranjal spots common sticking points, recalibrates pacing, and makes sure nobody drifts.
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.
As you near the end of the curriculum, calls shift to mock interviews — real FAANG interview pressure in a safe environment with direct feedback.
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.
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.
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.
Not for: People who want shortcuts, certificates without effort, or anyone not willing to code every day.
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.
Both plans include the full 16-topic curriculum with all 4 formats — lifetime access, study at your own pace. The difference is accountability.
