Very bad/ridiculous approach to interviews. It felt like you are not technically skilled cause you don't know by heart technical stuff you don't care to know by heart. Security guy asks you very specific things(even if is not your field of expertise) about configuration that you might not remember even if you've been here or there. Sort of questions: -Have you been to Paris? -Yes I have... -How tall is Eiffel Tower? -Eh... I don't remember... -Oh... You have not been in Paris. Oh... Let's move to the next Question... -What about London... Have you been to London? -Yeah... and I have seen the Big Ben... -Really... In what year was it built? -Eh... Don't remember... But I know its a clock with a big bell... it's in front of Thames River... -Oh... no... you have not been to London... So... what about you, do you have any questions? If you're a Tech Generalist, and know who Linus Torvalds is, but don't know what year he was born, this is not the company for you. (Oh... by the way... Ive been to Paris 8 times).
