1. Know your resume from beginning to end.
2. If you have gaps between work history, have an answer ready of what you did(be honest) because 9 times out of 10 they will make a comment on it.
3. Have some kind of answer ready in relation to the future. Some interviewers like to know what you want to do with your life! It could be things like upskilling your skill ( doing courses )in the future.
4. If you have hobbies on your resume, like reading or watching tv. Then know a bit about the author or something about your favourite tv show.
Finally just relax and arrive in time and it should go ok.
