I can assure you that the majority here won't be bothered whether you say "speed 180" or "speed 180 knots"...
Non-native speakers: yeah, I am one of those, too. I speak 3 languages. But come on, it is common sense that you should at least know the correct name and spelling of your potential employer. I am used to fuel truck operators writing our company name as "Net Jet" or similar, but I expect a pilot to prepare more thoroughly. First impressions count a lot, but I am also convinced that he will make it through the selection process if he's a nice and competent person, who you could imagine hanging out for 6 days in a row, no matter whether he calls us Netjet or Netjets.
