Be genuine. Be honest. Tell them why you are an interesting person. Don't just repeat what is on your resume. They have already read it. Don't tell them a checklist of your skills. Tell them a good story about yourself. The interviewer, especially the hiring manager, is looking for someone who will be a good fit on his/her team. If you come across as an interesting candidate in the first five minutes, you will have their undivided attention for the rest of the time.
Everyone likes a certain human element to come through. Every interviewer is looking for someone they can work well with. Technical skills can be taught. If you have certain areas that you are not very strong at, be upfront about it but always demonstrate a willingness to learn. Most importantly, make sure you give them a reason to remember you; to ensure that you stand out from the crowd.
