Try to look for something that goes beyond your personal role in the company, something you can praise, something that resonates with you.
I really like the job description and believe I can fit here, and bring some value to your team of financial analysts.
In my free time I like to run, read, and meet with friends.

Your goal is to convince the employer that you genuinely want to work for them, and that you have a good reason for choosing their offer (and not an offer of one of their competitors).
