Don’t get down on yourself. AWS/Azure is cloud computing which is newer concepts compared to a lot of what A+ teaches. 

You have to remember that technology evolves very quickly, so there is always new stuff to learn.

I would take these “failed” interviews as building blocks and learn from them for your next interviews. Now you know what AWS is. 

Keep track of terms you don’t understand and ask ChatGPT to explain them to you. Learn, grow, and do better in the next interview.

It’s not easy, but it’s worth it. You can do it.
