Yes, I called them back since the text said it was about a job. It's some company that found my resume online and wants to send me matches to it or something.
This number is a part of Applicant Services, a new service that matches up jobseekers with employment opportunities. We receive resumes of people seeking employment from all over the country. When you call in, we ask you for some basic information -- never your social security number or anything similar -- and match you up with jobs that meet your criteria for employment. We do this as an absolutely free service to jobseekers. There will never be any charge, and we will never ask you for any sensitive or billing information.
