Also made trade-offs list to cover during the interview.\n**Behavior:**\nThe most interesting thing here because I\'m not a native speaker and my English wasn\'t good enough to pass it, I suppose.\n\nSo, I decided to cover it during my English lessons. Made a spreadsheet and go through all possible questions together with my English teacher. He was really helpful not only in terms of English but also in terms of adjusting my answers to companies expectations.\n\nSo I really recommend him for LP preparation especially if you\'re not a native speaker like me. You can contact him through skype: **live:caiohpf**
