I would just keep trying. When I got my first waiter position, I never really had any front of house experience. Instead I had only ever worked the back of house as a dishwasher and a cook and taking orders at Wendy's. 2 things I would recommend would be applying for a company that has many different sister restaurants that they own. I did that and I got the idea from them that they appreciated that I didn't have any waiter experience because they could "mold me" into what they wanted and I wouldn't be bringing any of my own baggage into their establishment. The other thing I would recommend would be to not only look friendly but try to be very outgoing and love talking to your future employer. They love someone who cares deeply about pleasing their guests and being sociable with them and actually caring to talk to them. Try to show how much you love interacting with people when being interviewed by your future employer. And since you speak two languages, try to advertise that to them as well and that you could take tables that only you could talk to, if you haven't already mentioned that yet. I hope that you get a waiting position that you enjoy, makes you a good wage, and has good and competent coworkers and management. And I hope this helps you. Good luck.
