He called me to discuss my experience, one of which mentioned that I worked in an environment where my team managed "30,000+ servers". He took the opportunity to say something along the lines of "that's irrelevant, that's smaller than one datacenter in one of our regions".
I honestly have no idea why the recruiters from these places have such a superiority complex that they need to belittle people like that. It's not even the manager of the team you'd be working on, just some recruiter that probably doesn't have any of the skills/background the job they're recruiting for requires. Yet they need to make you feel small and worthless right out of the gate.
Is it just prepping you for how you'll be treated there? Trying to select for people that are okay with being belittled?
