All companies want to hire people who love this job, so you should be very clear about the answer to why you want this position. First of all, give some reasons why this role is very suitable for you (for example, I work in sales, because I like to deal with people and excel in interpersonal relationships). And then when it rises to the company level, why would you choose this company (for example, I have always liked those interesting advertisements made by P&G. I think you are doing great things to popularize a better lifestyle to everyone, so I think Become part of it).
