Idea is to design a kind of system where the system has to predict the candidate proficiency in particular area.

Basically there can different categories like

1. system design
2. DSA
3. full stack developer
4. front end developer
5. backend developer

System should test the candidate capability by asking some questions and conducting some tests - based on the performance of the user system should suggest him the area he/she need to improve or concentrate more and also suggest some notes which will be useful for them to prepare

these notes can be fed to system from different users - it will be categorized and stored in the system.

Also if possible we can include the kind of preparation required for different companies based on his current proficiency.
