You will finalize your foundational Windows application by connecting it directly to operating system events and hardware input. You will implement asynchronous timers, capture raw mouse and keyboard interactions, and use native Windows File I/O to persistently save user data to the disk while ensuring a clean, graceful application shutdowns across a variety of specialized scenarios.

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
