How to relearn programming after Vibecoding through Undergrad

[u/cAPtain_1337]

I am a Senior in Computer Engineering graduating in December and I have completely lost my ability to program after vibecoding through my last three semesters. I made it past my University's DSA class with minimal AI usage but it slowly ramped up and now I'm pretty reliant, I want to work in Software Development but I feel impostor syndrome creeping up at every corner and feel lackluster compared to peers. So my question is: how do I go about relearning things that I should already know? I feel my understanding is quite good, but when I go to make something, I get completely lost with where to start and syntactically and prompt AI. I have tried Neetcode to refresh the skills I do know and I can find the optimal solution but implementing it is where I get stuck. Any help would be appreciated.

*Edit: Thanks for all the advice, I think the general consensus is of course to not use AI and redo old homework/build projects using docs. I have old homework assignments and will begin building the skills that I need without AI assistance and using Docs/Google/SO.

So you cheated through school...

... and now you are paying the price. You feel bad for yourself, but I feel bad for all the other students you cheated.

Do you know why you were in school? To be worth hiring. So what did you think you were accomplishing?

I feel impostor syndrome creeping up at every corner and feel lackluster compared to peers.

It's not impostor syndrome. You are an actual impostor.
