The email comes from an unknown email address claiming that the part time job position, whether the recipient has knowledge of applying or not, has been offered to the recipient. There is a task to be completed in order to be compensated, and there is a list of personal questions such as bank information and address that the email is asking to be completed and sent back. This should not be trusted.
The job scam email is attempting to entice you to respond with personal information and also complete the task. Ultimately, the scammer is attempting to gather personal information and money from unsuspecting victims who respond back.
