A job offer letter isn't a contract. It doesn't require a signature and, as you've experienced, a signature doesn't guarantee a job.Through Online Job Offers, prospective employees can view, decline, accept and complete pending job offers. An employer may complete Form I-9 before the first day of employment if the employer has offered the individual a job and the individual has accepted. A company verbally offered me a job and I accepted it, I start next week. How do I follow up to thank them and ask for a formal offer letter? Congratulations on accepting your job offer!
