I hate it but it's how these things go. You only had a 3 week internship at school because that's what your school does at the end of your semester as a requirement for graduating? That's fine, on your resume that becomes "Spring 2024", people don't need to know it was only 3 weeks, they can think it was 3 months unless they explicitly ask you how long it was which they usually don't. It helped me land my first dev job years ago, it sucks but it works.

Exactly. In jobs they will find out if you lied about possessing skillset they require, especially if it's a critical one.

I can do it, but if it's like a small lie. I know something similar, where the learning part is very small and I'm not lacking any core knowledge.
