Study your resume & practice
Most of the questions in an interview are asked through your resume; hence, it is crucial to go through your resume and make it as clear and precise as possible. All the information that is given in your resume should be on your fingertips.
One of the most common practices for interview preparation is to speak in front of a mirror when you are alone. By speaking out loudly, you can surely enhance your confidence and will get you in a flow. Apart from that, you can also give mock interviews to someone who understands you. Mock interviews should give you some great practice.
Be confident and honest
Having faith in your own abilities is one of the keys to success. Take long breaths before your interview, which should help you to be calm. There is a saying that milk helps you control your anxiety level. Have a gentle smile on your face during the interview and be your natural self, instead of pretending what you are not. People who are going to take your interview would be much more experienced and they would get to know if you are faking things. Honesty always has a good impression on the interviewer. If you have any weakness, you should have the courage to admit that.
Dress well and relax
It is imperative for you to be presentable in the interview as it does have a psychological impact on the interviewer. Buy a nice formal dress a day before the interview and use a nice fragrance. Good dressing helps you behave more confidently as well.
Do not overburden yourself with the interview pressure and try to relax and engage in different activities a day before the interview, which should help you answer the questions in a more effective manner.
