You want to make sure that you know in advance what type of position the company is hiring for and answer the question in line with that. For example, if it is a temporary position, then note that you are aware that it is a temporary position and that you would stay through the end of your contract with the possibility of being open to further employment — if it is offered. In general, you want to show that you’re not going to just jump at the next big chance, leaving this company in the lurch, so use this question to explain your commitment and loyalty to the projects that you take on.
