Contacted by recruiter via iHireTechnology. She tried contacting me via my yahoo email, after I applied 3 weeks ago via their LinkedIn job posting. She text messaged me to alert me as I had not noticed her email due to spam. Her email did not include job details or even text about the specifics of the job, but did tell me it was for Simplify3D, from which I located the listing at LinkedIn and the fact I had in fact applied there.
