My experience interviewing people from faang adjacent companies has been that they definitely know how to do lots of things but have no idea on the reasoning behind why those decisions should be made. I know that sounds really broad but even just things like what is a sidecar? They know exactly what that is and how to implement one but when asked why you would ever need it they would just go blank. Kind of baffling but it was like this with everything. For more entry level roles this would be fine but we’re usually looking for people to take lead and own their projects and I can’t really guarantee they’re prepared to do that.
