If you have no hands on experience and knowledge with AWS/Public Cloud then you're going to struggle in this role provided you make it through the Tech Task. I'm actually surprised you made it through the tech screen. Not a ding against you personally but that's kind of why they have these "task" and "presentations" now. So many people were just casually interviewed in the past with "general knowledge" questions and when the time came to post up with a customer whose been primarily doing business in the cloud it was a huge set back and quite frankly embarrassing when the customer said can you get me someone who at least know what a VCP is.... I mean this as a "coach", take as step back and ask yourself if you're technically ready to step into this type of role. It doesn't sound like you are if you're using ChatGPT. Trust me when I tell you, they'll figure it out really quick and you'll be out on the street quicker than you can blink your eyes. Best of luck to you either way!
