The gap nobody talks about
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.

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.

SDE-2 → SDE-3, Razorpay
The per-question breakdown after every check is insane. I finally understand why I'm losing marks on trade-off questions, not just that I'm losing them.

Backend Engineer, Zepto
roadmap.sh showed me what topics exist. KnowEase told me how good I actually am at each one. Those are completely different things.
Rohan Sharma
Fresher → SDE-1, a Bangalore startup
Three weeks, 8 checks, score went from 52 to 79. The practice blitz sessions are addictive — short enough that I do them on my commute.
