But how do you know that you make the right choice? First, once you decide on an agency, search for as much information regarding its activity as possible. Secondly, when you go over for an interview, ask all the questions you have and never leave until you are sure you know everything regarding your activity. And third, ask about your contract and what it will include. Be sure to read it once, twice, or even three times if you are unsure everything is crystal clear.
