How to answer the question “why are you looking to leave your current company?”

I’m looking for more responsibilities.

Why are you not getting that at your current company?

There is some and it’s good. It is not at the pace that I need at this stage in my career.

Critique my answers please?

I find recruiters never look down on someone who is looking for more responsiblity so stick with that.

Also avoid talking down about any employer or person. That can come off poorly
