About

TheLearningLoop teaches software and IT concepts, starting with data structures and system design, through interactive simulations. Each idea is then connected to where it shows up in real systems and the interview questions it tends to produce.

Lessons are written and reviewed by TheLearningLoop's team, each checked against primary sources and against real interview questions before it is marked "asked often." Every lesson shows who last reviewed it and when.

Lessons are free and supported by ads.
