I have checked out the company they say they represent and I believe Amerigroup is legitimate. However, I question that the Online interviewer actually works for this company as stated. They offered the position after an online interview and stated I should join them online at 8 a.m. the next morning (10/28/16) and that I would be working at home until they completed a facility in my area...they would send me a check to purchase what software I would need to perform the job from home. When I checked the company out they have offices in West Palm, Fort Lauderdale and Orlando, FL I am in Stuart, FL which is about 45 minutes from West Palm. Just doesn't feel right!
If the job is something like processing payments, it is probably a well-known money-laundering or similar scam.
I would independently look up the phone number for the company (ignore what the interviewer gave you). Phone them and ask to speak to HR. I would explain the situation and ask them if they can confirm the job offer over the phone - and in writing too.
Never phone from a landline directly after receiving a call from the interviewer, they can hold the line open and pretend to be whoever (e.g. a bank or an employer) they told you to phone. Use a different phone or call a relative or friend whose voice you recognise first, then make the important calls after 30 minutes.
Never forget that a check can bounce weeks after it is credited to your account (after it appears to have "cleared") - you will be left owing the bank money. The people who sold you the special software they say you need, are the ones who benefit from this sort of scam.
If it sounds too good to be true, then it probably is. The red flags for me are:
- It is implied in your question that you didn't apply to them, but they got in touch with you. Unless a recruitment consultant or someone you know makes contact with you, then it is unlikely to be legitimate
- Not meeting a real person, face-to-face for interview is a big red flag. Even if someone reaches out to you electronically, then it is best to meet the hiring manager face-to-face before accepting an offer
- Offering that you work from home is unusual. I've been fighting to work from home with my employers for 7 years now, and they haven't budged an inch. Working from home is a red flag here, because it may imply that there isn't a real office or a real business involved
- Offering to send you a cheque to buy equipment just sounds wrong
