This week DSA Tracker shipped its biggest batch of the year: a sheets hub, company-wise sheets, revision confidence tracking, and verified platform profiles. This post is the changelog — and, more importantly, an honest note on where the company data comes from, because that's where most 'company-wise' lists quietly cut corners.
Search for 'Amazon DSA questions' and you'll find hundreds of lists. Almost none say where their tags came from. Many are copied from each other; some are simply invented. We didn't want to add one more.
Our company tags come from exactly one place: each problem's own GeeksforGeeks page, which publishes the companies that have asked it. We fetched every GFG-linked problem in our 370-problem set and recorded what the page said — along with the source URL and a timestamp for every single tag. Problems whose home platform doesn't publish tags publicly (LeetCode keeps theirs behind Premium) are not tagged at all rather than guessed.
The result: 12 company sheets that clear our minimum bar — Microsoft (43 problems), Amazon (37), Flipkart (23), Samsung, Adobe, Google, NPCI, MakeMyTrip, Morgan Stanley, Accolite, Cisco and D-E-Shaw. Smaller than the internet's '200 Amazon questions' lists? Yes. But every problem on ours has a receipt.
Problems now start from a Sheets page: the three source sheets you already trust (Apna College, Love Babbar 450, Striver A2Z) with your live progress, the new company sheets, and our role-based twist: 24 role-based sheets that re-order the same problems for the job you're actually interviewing for.
Marking a problem solved says nothing about whether you could solve it again. Every problem now has a confidence rating — Struggled, Tough, Got it, Nailed it — with a full history per problem, so your revision passes have a memory.
You can now connect your LeetCode, Codeforces, CodeChef, GeeksforGeeks, AtCoder, HackerRank, and GitHub handles. Stats are fetched from each platform's public data at sync time — never self-reported — and LeetCode sync also imports your recent accepted solutions into your tracker progress. One honest limitation: LeetCode's public API only exposes your 20 most recent accepted submissions, so the sync accumulates as you re-run it; it cannot backfill your whole history. Flip on your public profile and you get a shareable page with your role, readiness and verified stats.
DSA Tracker is a free, not-for-profit tool. We don't create problems — we organize the excellent free content that already exists and give full credit to its authors. That only works if the organizing itself is trustworthy. Verified tags, sourced links, and stated limitations are the whole point.
Amazon is the most predictable big-tech loop a fresher can prepare for — but only if you know its actual lean: grids and graphs over exotic DP, a debugging section in the OA, and Leadership Principles that quietly decide SDE-1 offers. Here's the deep, Amazon-only plan.
LeetCode Premium's company tags cost roughly $35/month — and the moment you have an interview date, that paywall feels mandatory. It isn't. Here's how to reconstruct most of that signal for free, and the one thing Premium genuinely does better.
