Now a days getting a job is pretty hard and I can imagine how bad you would feel if you got the chance to get that job of your dreams but you didn't get it because of some little factors that you change in some minutes. Most people find it really had to get a job even when the opportunity presents itself. It could be because of the way you act, the way you dress or the way you talk and communicate your ideas to the interviewers. These little things can go a long way to giving you an edge and ultimately giving you the job. I am going to assume your resume/cv is in good shape . I am just going to go over some little tips that could help you in most job interviews.

1. Know the Company whose job you are getting interviewed for. You could check their websites or social media accounts to find out a little bit more about the company. This could could a long way in helping you later.

2. Beef up your cv/resume and make sure it is ready. You may want to take a spare printed copies for emergencies or stories that touch.

3. Dress well. This is one of the reasons you need to know the company you are getting interviewed for. So that you would know if the company's dress code is strictly professional or if they allow casual dressing. If you are still not sure of what to wear you could hang out at a restaurant or a fast food joint near the company and try and notice the dressing of the employees. You may think this is taking it too far but you really want this job and may not want to lose it because your dress code was wrong.
