You have been solving problems for months — LeetCode streaks, random YouTube tutorials, copy-pasting editorial solutions you only half understand. And yet, the moment a live contest starts or an interviewer asks something slightly unfamiliar, the whole framework collapses. The truth is, competitive programming and interview preparation both have a structure, and learning without that structure is why most aspirants plateau.
GeeksForGeeks has launched its biggest June 2026 sale with up to 67% off on CP, DSA, system design, and full-stack courses — and with coupon code ZOUTONS50, you can save up to ₹2,500 on the platform's best-rated courses. Whether you are targeting a Codeforces Div. 1 rating, cracking FAANG interviews, or preparing for GATE CS 2026, there is a structured course in this sale built exactly for that goal.
We have reviewed the entire GFG course catalogue and shortlisted the 13 courses that offer the best ROI for June 2026 — ranked by topic depth, problem quality, instructor credibility, and how well they map to actual hiring and contest outcomes.
"If you only buy one GFG course this year, the DSA Self-Paced is it — 200+ hours, lifetime access, and a curriculum that mirrors exactly what top companies test."
The DSA Self-Paced Course is GeeksForGeeks' flagship offering and the most bought coding course in India. It walks you from arrays and strings all the way to advanced trees, graphs, and dynamic programming — every topic mapped to real interview questions from Amazon, Google, and Flipkart.
"CIP is not just DSA — it bundles aptitude, operating systems, DBMS, and mock HR rounds, which is exactly why 1 lakh+ students have chosen it for placement prep."
Complete Interview Preparation is GFG's all-in-one placement bundle. It covers technical (DSA + CS fundamentals), aptitude, and soft-skills preparation in a structured 6-month roadmap designed around actual campus and off-campus hiring cycles at top MNCs.
"Live instruction makes a real difference — when you can ask your doubt in real time and have a mentor push you past the 'I'll skip this for now' moment, your progress compounds fast."
Unlike the self-paced version, the DSA Live Course gives you scheduled classes with a dedicated instructor, live doubt-clearing sessions, and a peer cohort to compete and collaborate with. All sessions are recorded so you never miss a class.
"This is the course that will take you from Codeforces Div. 3 to Div. 1 territory — the problem set alone is worth the price, and the STL + segment tree modules are class-apart."
Purpose-built for competitive programmers, this bootcamp covers every topic you need to climb ratings on Codeforces, LeetCode, and AtCoder. From C++ STL tricks to segment trees, advanced graphs, and combinatorics — the curriculum is built by red-coders who know exactly where beginners get stuck.
"DP trips up 90% of candidates in FAANG interviews — this course teaches you the underlying patterns, not just the answers, so you can solve problems you've never seen before."
Dynamic Programming is the single hardest topic in competitive programming and technical interviews. This masterclass teaches you 25+ DP patterns from knapsack and LIS to bitmask DP and digit DP, with a problem set sorted by pattern so you build real intuition rather than just memorising solutions.
"Graphs show up in 40% of FAANG on-site rounds — having a dedicated course that goes all the way to network flow and topological sort gives you a genuine edge."
Graphs are everywhere — social networks, routing algorithms, dependency resolution, and nearly every hard LeetCode problem above medium difficulty. This course covers BFS, DFS, Dijkstra, Bellman-Ford, Floyd-Warshall, MST algorithms, topological sort, and network flow with 80+ problems to cement each concept.
"System design is the gatekeeping round that filters for senior roles — this live course covers 30 real-world architectures with mock interviews that feel exactly like the real thing."
The System Design Live Course prepares you for senior software engineering interviews at FAANG and product companies. You will design real systems — URL shorteners, Twitter feeds, Netflix-scale video streaming, WhatsApp-style chat, and 25+ more — covering both high-level design (HLD) and low-level design (LLD) with dedicated mock interview rounds.
"Starting your data science journey with this course means you build on a solid Python foundation before touching ML — that sequencing is what separates someone who actually gets hired from someone who just watches tutorials."
This course takes you from Python basics to real-world machine learning applications in a structured, project-first curriculum. By the end you will have built 15 complete data science projects — from EDA and visualization to regression, classification, and clustering models ready for a portfolio.
"Java + Spring Boot is still the dominant stack in Indian product companies and MNC service firms — learning it properly with microservices and Docker means you're hirable on Day 1."
This full-stack Java course covers the entire modern backend ecosystem: Core Java, Spring Boot, REST APIs, Hibernate, Microservices architecture, Docker, and deployment on AWS. You will build five production-grade projects, each simulating a real business requirement, with code reviews included.
"C++ is the language of competitive programming, and knowing the STL inside out halves your coding time in contests — at under ₹1,000 this is the best first investment for a CP journey."
Designed specifically for students who are new to competitive programming, this course starts from C++ fundamentals and builds up to advanced STL usage — vectors, maps, sets, priority queues, and algorithm functions that eliminate the need to write custom implementations in timed contests.
"GFG authored a huge chunk of the study material that GATE aspirants already use for free — the paid course takes that depth and adds structured schedules, mock tests, and doubt sessions that free content simply cannot match."
Targeting a score of 60+ in GATE CS 2026? This course covers all eight core subjects — Algorithms, Data Structures, OS, DBMS, Computer Networks, Digital Logic, TOC, and Compiler Design — with topic-wise video lectures, 2000+ MCQs, and full-length mock exams calibrated to the actual GATE difficulty.
"MERN is the most-hired full stack in Indian startups right now — this bootcamp gives you a portfolio of 10 projects which is exactly what a hiring manager at a Series B startup wants to see."
This end-to-end web development bootcamp takes you from HTML/CSS basics to a deployable full-stack MERN (MongoDB, Express, React, Node.js) application. The curriculum is structured around building ten real projects, so by the time you finish you have a portfolio rather than just a certificate.
"The jump from 'I completed Andrew Ng' to 'I can build and deploy a real ML model' is exactly what this course bridges — eight projects that span NLP, CV, and tabular ML with industry datasets."
Moving beyond theory into production-ready machine learning, this advanced course covers supervised learning, unsupervised learning, ensemble methods, neural networks with Keras/TensorFlow, NLP with transformers, and model deployment on Flask/FastAPI. Every module concludes with a project using a real-world dataset.
