After CV was sent by email yesterday, she got this reply from her friend's indicated email address (this was after she got an sms from HALLIBURTON asking for a medical certificate that has to be submitted latest 6pm today):

I was informed that u have been ask to submit An approved medical Certificate, and I faxed a colleague who pleaded to a Reputable Halliburton International Medical Doctor, Dr Mrs Remi Taiwo for her help, I was notified that she is on a brief official assignment in the United States of America, Urgently send a message over to her through her facebook link {www.facebook.com/dr.remi.taiwo1} and also an email through {dr.remi.taiwo@gmail.com} do send her a message through both mediums and we Pray for her swift response, of also importance is her phone contact over there is {+1 561 908 3578} Urgently email and Facebook message or call her, plead 2 her that I said she should assist u in preparing d document because it is the only thing that would stand between your employment along with your message do not fail to include your phone number because I do not want us to miss this opportunity. Plead to the Doctor that I said she should also assist you in submitting it to the relevant offices as she have already been made knowledgeable of the company’s given deadline of submission, I am convinced that as a senior Medical personnel with our Company she would give instructions on how it could be prepared & also submitted without us missing the deadline. I am presently in our company? Of-shore location on our annual official exercise and would be back to shore on 29-09-2013. I will call you on arrival as the network reception over here is very poor. I sincerely hope that you would be diligent to your duty when you are eventually employed because if you are not that would deprive me from referring others for such opportunities in the future.
If peradventure her phone couldn't go through at the moment because of the time difference between the USA and NIGERIA then you would have to send her an email message as well as a text message without delay considering the fact that the document must be prepared Urgently.'

I'll keep you posted of developments.

But has anyone seen anything similar to this this in recent times?

My take is just keep playing along till U're asked to pay an amount. A so-called professional that goes off-shore and still spells it as "of-shore".

Sounds very fake to me. Beware man!
