Job Interview Tips

By reaching the interview stage you have knocked out the competition and can deduce several things. Firstly, that the company recruiting new personnel is interested in what you have to offer, they have read your CV and they have liked what they have seen.

You will also have lost much of the competition, as only approximately 15% of applicants reach this stage.

Having established that you have the fundamental qualifications for the job, you have to build upon this and impress the interviewers with your personality. The purpose of an interview is for the employer to meet you in person and evaluate whether your personality will fit into their company.

For you, an interview is a chance to impress and see if this company has an environment in which you would like to work.

First impressions Counts

Research by psychologists has shown that people decide what they think of you within four minutes of a first meeting, therefore is very important to make a good impression right from the start.

Get all of your preparation out of the way well in advance, and allow plenty of time to get to the interview so that you arrive in a cool calm state. Arrive ten minutes early and use the bathroom facilities to smarten your appearance. You will not be so nervous if you are well prepared and look your best.

Confidence is the magic word, if you are confident then you will be relaxed and able to talk lucidly about yourself, you will be able to look the interviewer in the eyes, you will not fidget - you will have the potential to clinch the job.

If you are not feeling very self-assured just think, you wouldn't have reached the interview stage if you didn't possess the attributes that the company desires.

Looking your best and being well prepared should help, so that when you meet the interviewer you will be able to greet them openly with a smile, look them in the eyes and shake their hand.

Don't let confidence come across as arrogance. Excess confidence can come across as arrogance can come across this way and it's not an attractive trait for the employer as it implies that you are not a good team player.

Attractive features that are desirable to all employers include:

Confidence in yourself

This can be expressed in so many ways. Look the interviewer in the eyes, shake their hand firmly. Be chatty and lucid, sit with good straight posture with your hands on your lap, be precise in your answers do not 'Um and ah'. Confidence comes with experience, so tell the interviewer about difficult situations that you negotiated in your previous jobs, perhaps even mention your world travels or a time you held a position of power within an organisation.


To express approachability be friendly and open, smile and pleasantly greet everyone you are introduced to. If you trained other personnel in a previous job, or were a counsellor at college, recount an occasion when professionally someone came to you with their problem.

Sense of humour - but don't over do it

Do not set about telling jokes, but be responsive if the interviewer makes a humorous comment (even if it is not very funny). If you can subtly incorporate humour which is not at the expense of anyone else then do so, but bear in mind that this is a business interview and you should be professional.


These qualities cannot be really seen in a person, but you can recount the times in your previous jobs that you have held positions of responsibility. For example any job in which you were responsible for personnel or if you were a youth leader at a community centre.


These qualities are linked to confidence, but in addition show the employer examples of times you have used these skills and have prospered as a result. For example, you worked on a software solution to a work problem in your own time and it turned out to increase the efficiency of the task by 60%.

Body language

A first impression can be greatly influenced by a person's body language. Be open with your body language, ie, donít sit with your arms folded. Look at the interviewer when you are conversing with them and smile at them so that you look like you are enjoying the interview (even if you are feeling nervous).
