Determining whether a prospective hiring company is legitimate requires careful cross-referencing and background research to protect yourself against common employment scams. First, look up the company's official website, verify that their communication comes from a matching corporate domain rather than a free webmail service, and ensure their physical office address matches public business registry records. You should check independent business review platforms, employee forums, and official corporate registration databases to confirm their legal standing. Be highly suspicious if a recruiter requests payment for training equipment, background checks, or visa processing fees, as legitimate employers never require candidates to pay for securing a job. Conducting a live video interview and independently verifying the interviewer through corporate channels provides additional confirmation.
