In any tightly run job competition, when the top candidates for the position have equal qualifications, you will find that the job offer will go to the candidate that is intelligently enthusiastic.
The major problem for most job candidates is that they find interviews to be stressful events, and when under stress, their defenses either go up and get buried under a stiff wall of professionalism, or they start blubbering about. Either of the two scenarios can get in the way of winning the job offer.
When attending a job interview, the usual thinking is that the more enthusiasm you can display, the better. After all, what firm wants to hire someone who cannot even pretend to get excited about an interview for a few hours? Don't go overboard. It is possible to be too enthusiastic.
Over-enthusiasm can be noted when you speak too quickly, when asked a question, or when you start bulldozing the recruiter with all the accomplishments that you have made in your career.
The moment you start acting this way in any interview, you will have entered what recruiters refer to as the exhausting mode. You don't want your interviewers to be tired of you before the interview is over.
To ensure that this does not happen to you on your next interview, you can do the following:
When you feel yourself beginning to panic, take a moment to breathe in. It will help you calm down and at the same time provide you with a moment to regain your composure.
When you talk too quickly or loudly, you run the risk of wearing out the interviewer just from listening to what you have to say.
A hiring manager is looking for someone that he or she would like to work with in the same environment.
Therefore, when your energy strikes them as faked, or exhausting, instead of being inspiring, they are more than likely going to give you a pass on the job offer.
As human beings, we are our own worst detractors. In case you overdo it in an interview, and miss the job offer, try to look at it from this angle: you might have been a bad fit for the firm.
In today's work environment filled with disconnected workers, a different company could see your enthusiasm as a benefit for their firm.
