Never go drunk to an interview.Never smoke in front of the interviewer or in the company campus. See for smoking zones and smoke there if you have already got addicted.Smoke only if the interviewer himself offers you. It is always better if you don’t smoke.
Go very well dressed to the interview. Don’t be underdressed at all. Neat shoes, neat suit, good tie everything matters. Use of deodorants is always suggested. If you have the habit of putting scents, apply mild scents. If the smell is very strong, the smell may give the interviewer a headache. So use of mild scents is recommended.
Your first impression is made within the first 30 seconds of the interview. So be your best during this time. The way you wish, the way you sit, the way you speak, everything matters. Ask, may I get in before you enter the room, ask him, if you could sit before sitting, don’t be very stylish when you speak. You are not here to show off that you are very hap, but you are here to get a job. Remember this, all the time.
Don’t leave the interview without knowing what is going to happen next. You can gently ask him, when could you here something positive from the interviewer’s side or you could ask when is the next round of interview. Never leave the interview in the middle without knowing his next action.
Be careful when you use words, never use words like fuck, screw etc. These are bad manners. You will be rejected within no time. (These things are told in this article only to avoid people from making these common mistakes).
Be very professional when you speak to an interviewer. Never flirt with her if she is a woman. Stay far and answer to questions.
Speak very clearly with a lot of clarity on your thoughts and have a very convincing voice and body language.
Never be arrogant. Listening to the question properly before answering is very important. If you have not understood the question properly ask for it and give an apt answer. If you have not understood the question properly the interviewer will think that you’re listening and understanding power is zero.
All the very best for your interview.
