This company doesn't recruit via email. Check this out, from their own website:
It has come to our attention that fraudulent job offers are being sent via e-mail by persons claiming to be from Schlumberger or WesternGeco.
In the e-mail, prospective employees are told to obtain immigration documents. They may be referred to an organization that requests fees for processing them. In some cases they are told they will be reimbursed for all the costs.
These communications are fraudulent.
They do not originate from Schlumberger or WesternGeco.
They are a scam.
There are three quick ways to recognize a fraudulent job offer:
Neither Schlumberger nor WesternGeco will ask for any payment as part of the recruitment process; not for immigration documents, insurance, or any other purpose.
Neither Schlumberger nor WesternGeco uses e-mails to make job offers prior to a formal interview process.
Prior to employment offers, prospective employees are always invited to an interview with Schlumberger or WesternGeco personnel.
If you receive a fraudulent proposal, we would advise you to contact your local police and provide them with any information you may have from the senders (e-mail addresses, bank account into which the money was to be paid, etc.). Additionally, forward the e-mails you received to Report-Job-Scam@slb.com.
