colectors debt=harassment

I got a call two days in a row from this number.  They say they are American Income and they have some career opportunities.  It is a live person talking and leaving a message.

Message left on my voicemail:  "Hi, this message is for Melissa.  This is Jessica with American Income.  I'm calling regarding a resume you have posted over monster.com.  Our company is currently hiring for career opportunities of our sales and marketing division.  I'm holding an interview Thursday at 10:30.  Please give me a call back at 281-558-7776 ext.334.  Thank you."  I wanted to look up the company name & phone number before I returned the call.  I came across this website right away.  Thank you for the warning!
