By setting your job matching preferences, you can allow employers to find you based on some skills or certifications you've listed in your profile but not others.  This can be helpful if, for example, you have welding as a skill on your profile but you're now a Welding Inspector and you just want to be considered for jobs that involve welding inspection.

First, enter a brief description of the job you would like to do. Here are a few examples.

1. I'm looking for pipeline inspection work.

2. I'm certified as a UT inspector, but I'd like the opportunity to learn Phased Array.

3. I'm currently a welding but I'm looking to get into welding inspection.

Next, take a look at all of the certs, qualifications, or skills in your profile.  Tap/click on the ones you want to hide from employer searches.

For example, you may have welding as a skill in your profile but would rather do inspection work. Just click/tap the welding tile to turn it gray. 

Employers will no longer be able to find you based on this skill.
