Do not try to be a smart aleck
Do not act like a know-it-all. Remember they take interviews of hundreds of people and therefore can easily understand when someone is lying. The rounds can be technical or non-technical and your answers may vary but if you are bluffing then chances of getting caught in the technical round are far more. Even the interviewers know that you may not know everything.
Therefore be honest in what you say and backup confidently about everything that you have mentioned in your CV. Interviewers appreciate honesty but if you do not know the basic terms or techniques of your career then it may act negatively on your side. Hence be careful as to what you speak in front of them and learn how to crack interview.
