I hate to say but...you should have stuck on the basic tasks a bit longer, gringo.
I cleaned floors and parked cars for years in the US, learning english
Unless you are LAN's CP why does it bother you so much if someone ask for a tip, a contact or an email address trying to have that bit of an edge on more experienced and competitive guys and get his/her CV looked up first? Did you get your call out of the blue while cleaning floors and parking cars and filled applications in your time-off only?
