The first impression you make on a potential employer is the most important one. The first judgement an interviewer makes is going to be based on how you look and what you are wearing. That's why it's always important to dress appropriately for a job interview.
Dress for the Job or Company
Today's casual dress codes are not suitable when you interview. It is important to know what to wear to an interview. Whether you wear a suit or something less formal depends on the company culture and the position you are seeking. Choose your outfit carefully because it's very important !
Listen to the interviewer
From the very beginning of the interview, your interviewer is giving you information, either directly or indirectly. If you are not hearing it, you are missing a major opportunity. Good communication skills include listening and letting the person know you heard what was said. Observe your interviewer and try to show him that what he says is really important.
Don't Talk Too Much
Telling the interviewer more than he needs to know, could be a fatal mistake. When you have not prepared ahead of time, you may ramble when answering interview questions. Prepare for the interview trying to make dialogues.
Don't Be Too Familiar
The interview is a professional meeting to talk about business. This is not about making a new connection or even worse a new friend. Your level of familiarity should mimic the interviewer's demeanor. It is important to bring energy and enthusiasm to the interview and to ask questions, but do not overreact.
Don't try to show off
Attitude plays a key role in your interview process. There is a balance between confidence, professionalism and modesty. Overconfidence is as bad, if not worse, as being too modest. Try to find a balance and to show that you are smart and confident.
It's ok if you have questions
Most candidates answer, "No." They don't have any questions at the end of the interview. Wrong answer. Part of knowing how to interview is being ready to ask questions that demonstrate an interest in what goes on, in the company. Asking questions also gives you the opportunity to find out if this is the right place for you. The best questions come from listening to the interviewer all the time. Show your interest !
Try to have the three C's
Reflect the three C's during the interview: cool, calm and confidence. If you know you can do the job, let the interviewer believe it too. By these 3 C's it's easier to do it. Never use words like "please" "hire me" etc. Look directly in the eyes and so that you mean every word you say.
Prepare yourself to answer which is your greatest weakness
However, this question has become a cliché for a reason. Interviewers continue to ask it even though they know they are unlikely to get answers that are 100% honest. Why? Because the way you answer a question about your weaknesses is very telling. You may not even realize what you are communicating when you answer this question
Yes, You Should Send Another Thank You Email
You may have a second chance. This means you should send out another round of thank you notes when the interview is over. Before you leave the interview, grab a business card for the person (or people) that interviewed you and follow up the same way you did in the first interview. This is going to be appreciated.
I can count on one hand the number of people who wrote me a thank you letter after having an interview, and I gave almost all of them a job.
