The gap nobody talks about
Courses, roadmaps, and LeetCode grinders all share the same blind spot.
Courses teach. They don't measure.
You can finish every system design course and still blank in the interview. Courses build knowledge — they can't tell you if your Caching is at 43 or 87.
"I finished the course"
Your Caching dimension: 43 — drill it now
Roadmaps are lists. Not diagnostics.
roadmap.sh tells you what topics exist — not what you're weak at. Without dimension scoring, you're studying in the dark.
Study everything, beginner → advanced
Weakest gap: Reliability (41). Fix that first.
You find out in the interview. Too late.
Interview feedback is final. KnowEase moves that feedback loop weeks earlier — at your pace, with clear scores, before the loop.
"You struggled with trade-offs" — post-rejection
Trade-offs: 58. 3 sessions to close it.
Process
How it works
Pick a role or topic — free
Choose a role (ML Engineer, Backend Engineer) or jump straight into a topic (System Design, MLOps). Answer 3 questions about your current level and goals. We build your personalized roadmap — ordered by your gaps, not alphabetically.
System Design
Caching · Check result
Study modules, take learning checks
Each module has curated content and a learning check. Complete a check to get dimension scores — not a pass/fail grade, but a breakdown of where you're strong and where you're leaking points. Scores update your roadmap priority in real time.
Track readiness, know when you're ready
Your dashboard shows dimension scores over time, a streak, and an ETA to ready based on your weekly hours and goal. Practice blitz drills for weak areas. Re-take checks to confirm improvement. Know exactly when you're ready.

Try it — one question, right now
No signup needed. Answer a real check question to see how dimension scoring works.
You're designing a rate limiter for a public API that handles 10M requests/day. Which approach best balances accuracy and performance at scale?
Dimension scoring
Dimension scoring. Not one number.
Most platforms give you pass/fail. KnowEase shows you exactly which dimension is weak — and by how much. Your radar updates after every check, across every topic.
System Design
Consistency at 45 is the gap to close first.
Social proof
What engineers say
From freshers to senior engineers — real scores, real outcomes.
I'd done mock interviews but never knew which dimensions were actually weak. KnowEase showed me Reliability was at 41 — drilled that for two weeks and cleared the loop.

Why engineers choose KnowEase
LeetCode tells you if your code passes. roadmap.sh tells you what topics exist. KnowEase tells you exactly where you're losing points — and how to close the gap.

LeetCode tells you if your code output is correct. It cannot tell you that your Indexing dimension is at 43 while your Transactions is at 71 — two different weak areas needing different drills. Engineers who only use LeetCode pass the DSA screen and then blank in the system design or SQL rounds. KnowEase is the missing layer: it tells you exactly where you're losing points across System Design, SQL, and AI/ML — not just whether you passed a test case.
No video. No lectures. No 40-hour course sitting unwatched in a tab. A readiness audit takes 15 minutes, shows you your dimension scores, and tells you the single gap to fix next. The entire feedback loop is designed to fit a commute — short enough to actually do, specific enough to move the needle.
The AI scores your answer against a structured rubric across 6 specific dimensions — the same dimensions senior interviewers at Flipkart, PhonePe, and Razorpay use internally. What it can't replicate: communication style and whiteboard presence. What it does very well: consistently surface which of the 6 dimensions you're weak in before you walk in. Knowing you're at 45 on Consistency and 78 on Caching is more actionable than "I failed the round."
Yes — if you're targeted. Most prep fails because people study everything. Your first readiness audit (15 minutes, free, no card) shows your two weakest dimensions. Three weeks of drilling only those gaps moves scores meaningfully. Don't study what you already know. Start today.
Most platforms give you content. None of them tell you what you're actually weak at before you walk in. The difference is the score — not a pass/fail, but a 45 on one dimension and 78 on another. That number tells you exactly where to spend tomorrow's session. You can't improve what you can't measure.
Built for India first. Questions are drawn from Swiggy, Razorpay, PhonePe, Flipkart, and Zepto rounds — not generic AWS case studies. Scenarios involve UPI payment flows, food delivery dispatch, and ride-hailing matching. Pricing is in rupees. The platform is built by engineers who've interviewed at these companies.
The free tier is real — 2 full module checks, dimension scores, and access to the practice bank. That's 3–4 hours of genuine signal. Pro unlocks all modules across System Design, SQL, and AI/ML tracks, unlimited checks, the full question bank, and AI-graded open-ended answers. Upgrade when you're ready to go deep. No card needed to find out.
