Ageism is a real thing and it's a challenge for older job seekers. 

If you are in the job market by choice or you were laid off you need to be mindful of the conscious or unconscious effect of ageism on your job search. 

There is nothing you can do to completely hide your age, nor should you need to, however, there are a few techniques you can do to mask it so that you get interview opportunities and have the chance to sell your experience, skill set and value to the person on the other end before your age becomes a consideration.
