Go to an industry conference and mention something you heard on a panel. And do an online search of the company, its industry and its competitors. Some young whippersnappers think the over 40 crowd are one long lunch and a nap. Prove em wrong. Research the companies you re interviewing with, then go into your interviews with ideas.
Older workers are often more expensive and that turns some employers off.
Tell em they may be wrong. Ideally, you ve shown them you re worth every penny you want above your previous salary. But if money is the final obstacle between you and a hot new job, consider offering them options. And there are always options in lieu of cash. Don t let age-ism keep you out.
