"Honestly I have no serious goals. I'm not trying to climb the corporate latter, just do a good job at what I do until I hit retirement."

I'd say if you're in your 60s or maybe late 50s your answer might work and the interviewer might appreciate your openness. But if you're younger I not sure your answer would be wise.

agreed... if you're young make something up... doesnt necessarily have to be a lie, just show the best version of you!

Ahead of time, while you're studying for the interview, try to imagine what job would be a step or two above the one you're applying for. THAT's where you should want to be in 5 years (or at least that's what you say in the interview).

The answer must show your leadership potential, your ambitions.
For example, in next five years I’ll have made a significant impact to the company’s bottom line. You should be able to share what areas you can strengthening in the near term. Accent your interest in a long-term career in the company.
And DON’T SAY, that you want to head the company within the next 5 years.

You answered really well but why we should not sat that we want to rule the company within next 5 year .. does they take it as a threat.. just curious

Employers value forward thinking. Even if your goals aren't with that company, goals in general are important.

editing a bit. Cut out all the stuff that raises questions and emphasize and build on the stuff that sounds good.

Cut: No serious goals, Not trying to climb ladder, Hit retirement

Emphasize: Do a good job.

So talk about how you like to go to work and be challenged and solve problems, rather than just doing the same thing the same way every day. Talk about the satisfaction of learning the system or job and possibly - down the road - being able to improve how things are done - making a contribution. Give examples of previous jobs where things have worked out well (limit or leave out examples where you've been bored, etc). This makes you sound like a basically positive employee without making any claims that you don't really believe. Who knows, maybe you'll like a job enough that you WILL want to get ahead.

Good luck!
