Top YouTube channels for DSA prep
A high‑engagement thread listed the best 2026 YouTube channels for cracking interviews—NeetCode for core patterns, Abdul Bari for theory, Gaurav Sen for system design, and company‑specific channels like Tech Dummies and Exponent for tailored prep. The thread also pushed targeted practice by company (heavy graphs/DP for Google/Meta, more OS/distributed focus for some firms). (social post summarizing channels, company‑specific LeetCode patterns thread)
NeetCode’s flagship “NeetCode 150” lists exactly 150 curated problems and breaks them down by topic (e.g., 84 Dynamic Programming entries, 65 BFS/graph entries) on its practice page. (neetcode.io/practice/practice/neetcode150) Abdul Bari’s long‑running YouTube channel shows roughly 1.27 million subscribers and about 116 videos focused on core CS theory and algorithms as of early 2026. (youtube.com/channel/UCZCFT11CWBi3MHNlGf019nw) Gaurav Sen’s creator profile reports ~724K subscribers and a catalogue of deep system‑design case studies on YouTube, while his paid InterviewReady course advertises 242+ video lessons and a recurring discounted price point (e.g., $85 offer shown on course pages). (developereducators.com/channel/gkcs/; interviewready.io) Tech Dummies (Narendra Lakshmana Gowda) shows roughly 160–168K YouTube subscribers and a companion site that hosts modular system‑design lessons; the creator’s Forbes profile states the channel has helped “over 300,000 engineers” in career and interview prep. (youtube.com/c/TechDummiesNarendraL; forbes.com) Exponent’s YouTube presence and platform advertise coaching, mock interviews, and institutional licensing (Stanford/Yale/University of Washington referenced in course blurbs), and Exponent’s product pages and videos cite a large user community plus a members Slack with 10K+ peer users. (youtube.com/c/ExponentTV; tryexponent.com; youtube.com/watch?v=BpRJXHobQ0Y) LeetCode’s 2025 recap of most‑asked company topics shows concrete patterns—Google favored Dynamic Programming and Graphs, Meta surfaced many Tree/DFS problems, and Amazon repeatedly asked Arrays/Intervals and greedy/sorting patterns—listing specific example problems for each company. (leetcode.com/discuss/post/7417074/wrapping-up-2025-with-the-most-asked-que-7rsc/) Multiple community repos and tools aggregate company‑tagged LeetCode lists (for example, a maintained GitHub CSV collection and interactive company‑wise dashboards), allowing targeted practice by frequency and timestamp rather than random problem grinding.
