I know a lot of you work full time jobs, and have trouble finding time to study for your programming interviews.
When I was studying for Facebook, I put together this project so I could study while I was still at work: https://github.com/DanielHabib/terminal-based-comp-sci-quiz
The idea behind this is that no one reads over your shoulder when you are working in your terminal.
If anyone wants to add to the project, PRs would be welcome. It helped me knock down a few topics that were giving me quite a bit of trouble.
Hopefully it helps you guys as well!
