Interviewers push past the textbook answer. What holds up is intuition you built a little at a time, so Syswise makes the daily habit the whole method.
Follow a path from foundations to reliability instead of picking topics at random. Each topic moves from the concept to practice to a checkpoint before the next one opens.
Practice is not a random question feed. Start it from your mistakes, your weakest topics, the cards due for review, or the daily challenge.
Review mistakes
Requeues what you got wrong, spaced out.
Weak areas
Drills your lowest scoring topics first.
Cards due
Brings back cards when they are due.
Daily challenge
One fresh question, every day.
Your streak, XP and a daily goal set in minutes update after every session. Finish one to join the weekly league and climb from Bronze to Diamond.
Weekly league
The readiness view fills in as you practice. It reads your answers, not your mood, and points you at the next weak topic.
Readiness score
One read on how prepared you are, once you have answered enough.
Average mastery
Where you stand across every topic you have touched.
Weakest quarter
The topics quietly dragging your average down.
Topic coverage
How much of the map you have seen.
AI scored mock interviews: coming soon
Not everyone starts in the same place, so the app finds your starting point before it teaches anything.
Interview prep, general learning, or a specific topic you keep avoiding. Start from the foundations, skip what you know, or ask to be pushed.
A short design question and a quick calibration show where you actually stand, so you don't repeat what you already know.
You get a starting path built around your answers. The first lesson takes five minutes, and daily sessions stay that short.
Every answer comes with the reasoning behind it, because knowing why the other options fail is what you get asked about in the room.
Pick an answer to see the reasoning.
Five minutes a day. One design call at a time. Until system design is something you understand, not something you memorized.
Anything else? The feedback screen in the app reaches the team directly.
About five minutes. The first lesson takes five minutes, and daily sessions stay short on purpose so the habit sticks.

Finish a session to join that week's league. You rank on XP against other learners; the top of the table promotes and the bottom relegates, across Bronze, Silver, Gold and Diamond.
