PROBLEM: Person1: Any plans tonight ?

Person1: Well , I am wondering if we took a hang-out for a drink or something . You know , I just came back from a really tough interview . I was quite nervous during the interview . I really want to have the job . Right now , I am still a little on the edge . I am not sure if I could convince them during the interview .
Person2:Take it easy . It is all over now . How was it going , anyway ?
Person1: I don ' t know . I think I did well in the paper exams . I was prepared to answer a lot of questions , but they didn ' t ask those as I expected . To my surprise , the manager tried to talk about the Chinese poesy with me .
Person2:That ' s strange . But probably , it is the new interview technique they call it " Getting to know you more personally " . What about your answers ?
Person1: Just did my best .
