It is important you present yourself quite differently from the other job applicants. You should work toward it. Apart from this, even the interviewer might ask you what makes you different from others or what do you think you can offer that others cannot. Whenever you are asked this kind of question, or you want to prove such, just make sure you focus on your strength.
Therefore, create a strategy to present yourself in such a way that your strength is well revealed. Make sure you talk about what you have to offer concerning the role you are applying for in relation to the benefits it's going to bring to the company.
You can talk about the previous achievements you might have had that can be of help to the organization. One more thing that can distinguish you from others is to avoid comparison and talking others down. Just present yourself well, be precise, confident, and polite.
