Q: Lots of questions about AWS testing my knowledge. Anyone who has worked extensively with it or has one of their solution certs (and exp) should be fine. --- I was very impressed by their take-home practical. I'd say it was hard in that it took hours and they were using some services I wasn't already intimately familiar with. Conversely, I'd say it was "easy" since I didn't have to do whiteboarding or quiz answering (a technical interview practice I loath). I don't want to spoil it so I'll say this: you must have AWS skills. They required me to use intra as code tech. They also required me to do some very light software development. Finally, you should be familiar with containers on both the dev and ops side as well as a spot of Git and *nix command line. Oh, and you must be capable of following directions.
General questions about past experiences, a couple of general programming questions.
No surprises here, just standard knowing each other questions.
General questions around AWS and Linux
How you will do the deployment for different environment using Jenkins pipeline.
How would you use Azure Automation in conjunction with PowerShell DSC?
