How long are you looking to stay at this position if you were hired?

Recruiters hate wasting their time, effort, and resources on hiring people who leave the organization immediately. Don't mention plans of starting a business or of going abroad as such could raise a red flag for the recruiter.
An ideal response would go like this:
"I would prefer to stay long term, if possible. I think this role is a great match for my skills and experience and offers me a chance to grow professionally. I expect to be here for as long as I have the opportunity to make contributions."
