Senior Project Officer Question:

This is the part where you link your skills, experience, education and your personality to the job itself. This is why you need to be utterly familiar with the job description as well as the company culture. Remember though, it's best to back them up with actual examples of say, how you are a good team player.
It is possible that you may not have as much skills, experience or qualifications as the other candidates. What then, will set you apart from the rest? Energy and passion might. People are attracted to someone who is charismatic, who show immense amount of energy when they talk, and who love what it is that they do. As you explain your compatibility with the job and company, be sure to portray yourself as that motivated, confident and energetic person, ever-ready to commit to the cause of the company.
