No offense taken. If I didn't get burned (I guessed "burned" means to have observed this first hand countless times over 15 years in the industry), then how would I know it to be true?

You can know Java, but if the team is using mongo and you don't know mongo, then there is a problem - if you know java and mongo - but there is a react front-end, then there is a problem... get my drift. The industry is going with a "experience doesn't count - you have to know what I know or be good at faking it" kind of theme. It very prevalent.

I has to do with the article. Did you read it?
> This is still true at some companies, but I think it is changing...
"Changing" isn't good enough. Think about something horrible , anything, would you want it to be "changing", or would you want it changed?
