INFONEXUS's graph algorithms module is the most thorough coverage of Dijkstra, Tarjan's, and max flow I've found anywhere — including premium online platforms. The mock interview structure simulating Amazon's OA + phone screen + technical rounds was exactly how I prepared for my SDE-I interview. Cracked it first attempt.

The DP module at INFONEXUS broke every pattern I'd been stuck on for 6 months — Interval DP, Tree DP, Bitmask DP all clicked in 2 weeks. The instructor's approach of solving 5 variants of every pattern before moving on is what made it stick. My Codeforces rating went from 1100 to 1680 in 4 months.

I had 2 years of experience but was getting stuck at the DSA round every time. INFONEXUS's Advanced level fixed my weaknesses — I finally understood Segment Trees and Tries, solved Hard LeetCodes confidently, and cleared the Microsoft SDE-2 round that had blocked me for a year. Best investment I've made.

FAQ

Questions About
the DSA Course

Straight answers to what students ask before joining INFONEXUS IT Institute's DSA with C/C++ program.

No. The Basic level starts from C fundamentals — variables, pointers, memory management — before moving to C++ OOP and STL. Students with any programming background (Python, Java, JavaScript) join successfully. The first two modules are dedicated to C and C++ foundations before introducing data structures. Basic programming familiarity (loops, conditions, functions) is the only prerequisite.
C++ is the dominant language for competitive programming (90%+ of Codeforces/ICPC participants use C++) and is preferred in FAANG technical interviews because of its precise memory control and performance characteristics. C++ with STL gives you the fastest execution, the richest algorithm library (sort, binary_search, priority_queue, maps), and teaches you computer science fundamentals (pointers, memory) that make you a better programmer in any language. INFONEXUS students who learn DSA in C++ find it significantly easier to transfer to other languages.
Students completing all three levels solve 500+ curated problems — 150 in Basic (Easy to Medium), 200 in Advanced (Medium to Hard), and 150 in Professional (Hard + system design). The problems are company-tagged (Amazon, Google, Microsoft, Flipkart) and organized by pattern rather than random selection. Every problem includes a C++ solution walkthrough, time/space complexity analysis, and 2-3 variants to solidify the pattern.
Yes. The Professional level dedicates a full module to High Level System Design (HLD) and Low Level Design (LLD) — covering CAP theorem, database design, caching with Redis, load balancing, consistent hashing, and designing systems like Twitter, URL Shortener, WhatsApp, Netflix, and Uber. LLD covers design patterns (Singleton, Factory, Observer, Strategy) implemented in C++. System design is tested in SDE-2 and senior engineering interviews at all top product companies.
INFONEXUS graduates targeting SDE roles receive: ₹5–12 LPA for fresher positions at IT companies, ₹14–28 LPA at product companies and startups (2–4 yrs experience equivalent), and ₹25–40 LPA at FAANG and top unicorns. Students who reach Codeforces 1700+ and clear all 500 curated problems have received offers up to ₹40 LPA from Amazon, ₹34 LPA from Microsoft, and ₹26 LPA from Flipkart.
