Offer Letter
An offer letter is a document given to a candidate once they have been selected for a position. It typically spells out the salary package, designation, department, and other benefits the candidate will be entitled to if they join the company. It may also include a statement of at-will employment, a list of contingencies, and a confidentiality agreement.
A signed offer letter does not mean the candidate is legally bound to join the company. That said, in very rare circumstances, it can become binding.
