Maybe try getting an AWS certification. Just going through that process will definitely expose you to enough of AWS to answer any possible interview question, and would probably help get you pass any resume screening too. It worked for me, and I started out as an electrical engineer!
It definitely won't make you answer any possible interview question, paper tigers often have issues with putting things together, cicd, iam and practical IaC setups.
It's pretty easy to tell theoretical experience from actual experience.
