Exactly. If someone has "Cloud Engineer" in the headline of their resume instead of "Devops Engineer" it's already warning and worth probing. If someone has "AWS|VMWare Engineer" in their bio, it's a giant red flag to me. Sometimes it's people just being aware where they'll find demand, but often it's indicative of someone who will push their pet stack - and it doesn't matter if it's VMWare on-prem or AWS (both purely as examples; it doesn't matter which specific tech it is), it's equally bad if they identify with a specific stack irrespective of what the stack is. I'll also tend to look closely at whether people have "gotten stuck" specialising in a single stack. It won't make me turn them down, but it will make me ask extra questions to determine how open they are to alternatives when suitable.
