"I go to interviews just to see the pay on offer"

A couple of days ago, I read a rather interesting article, about a fairly senior executive, who, although happy in his current job, would still attend periodic

interviews, just to get a sense of his true market value and the pay on offer. https://lnkd.in/ewvxz8me

What do you think of this? Is this something you have tried too, or would be open to trying? Would love to hear your thoughts/views, whether you are a recruiter or a jobseeker or a candidate?
