Could anyone, please, share some light on the "low-key" introduction issue mentioned in the article? I work quite a few years in IT and never, during any interview or meeting, I've been introduced as anything more than just an engineer. This must be cultural gap, no doubt, but I'd feel weird if someone would detailed my career in front of other participants. Of course I have nothing against filling some details in by myself but only if applicable in given situation. Truth to be told I've never worked in Australia or US, but I did some job in two EU countries and in Japan and, as said, never encountered detailed introduction. Is this still a thing?
