I think this is TEK Systems

Voicemail from TEK systems, a recruiting company specializing in high-tech jobs.

I think I gave them my number a few years ago, so really this wasn't unsolicited. Just unexpected.

I got this call from "Tek Systems" and it sounded like someone from India and English wasn't his first language. I had been working with a recruter from Tek Systems and they log all of their calls. When I spoke with my recruiter he said that there wasn't a call logged in their system.

If you work with this company trust me on this you will KNOW who your recruiter is. If you have to change recruiters they will do a soft hand off to another recruiter by introducing you to them. Don't give any personal information to anyone calling from this number. Email or call your local office directly.

yeah, headhunter from Teksystems.
