Free heavy‑hitters for interview prep
A viral GitHub/Google Sheets repo now offers 200+ company‑specific interview questions with video solutions, Coding Interview University remains a 337k‑star CS curriculum, and ByteByteGo made all seven of its system‑design and ML ebooks free until May 1—new, concentrated resources for DSA and system design study. These assets stack practical problems, interview patterns, and system design theory into a focused prep pipeline.

A recently circulated company‑wise repo that snapshots LeetCode problems — snehasishroy/leetcode-companywise-interview-questions — lists per‑company CSVs with fields for difficulty, acceptance and frequency and showed a Feb. 21, 2026 snapshot with ~3.2k stars on GitHub. (github.com) A parallel maintainer project, liquidslr/interview-company-wise-problems, publishes CSV exports for dozens of employers and shows regular updates (last noted update metadata: June 20, 2025), the same format others reuse to populate shared Google Sheets and CSV‑backed web front ends. (github.com) The long‑running Coding Interview University repo by John Washam currently displays roughly 338k stars on GitHub and records 2,511 commits, with its README explicitly stating Washam built the study plan while preparing for and later landing an Amazon SDE role. (github.com) ByteByteGo’s site is running a limited promotion labeled “Offer ends May 1” for a free month of access, and its newsletter signup routinely delivers a free 368‑page system‑design PDF to subscribers. (bytebytego.com) Wider tooling built on these feeds includes searchable web front‑ends (e.g., a “LeetCode Company‑wise Questions” Vercel app indexing 1,000+ company entries) and dozens of creator videos that walk through repo exports and solution walkthroughs, amplifying the Google Sheets/CSV exports into video‑linked study pipelines.
