Why do you want to work with this company?

You need to go prepared for this interview question. If their working style suits yours, you can discuss it. If the job you are applying for is the next logical step for your current job, tell them that. Or, even something like you being attracted to their work culture or vision, can be a good response. Better yet, you can say how the job and the company align with your personal growth. This shows that you are looking for a long-term collaboration with the company.
