Answer this question by telling the interviewer what seems great about the firm, e.g., their services, initiatives, growth opportunities, and so on. Make sure to answer by providing evidence that you did your due diligence before the interview (e.g., by mentioning something exciting you saw on the job posting, firm website or social media pages), which demonstrates you are serious about working for this employer specifically and are not simply looking for any job. Link this evidence to your professional goals proving this position was made for you and it is one in which you will excel.

For instance, you can point to their seemingly friendly firm culture as per some specific programs or initiatives you came across on their website, and say how friendly and how much of a team-player you are - and that this is exactly the type of work environment you are looking for.
