Customer: Who should sign an offer letter first? The employer or employee?Need help drafting a job offer letter? 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? An Application Submitted message confirms that you have applied for the job. I accepted a job offer through an email but I have not yet signed the contract. Is it possible to back out of the job. 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.
