Many companies present an offer letter as a final tool in the hiring process.
While the practice is more common in larger companies, growing businesses also employ this tool. Some job candidates will request a formal letter to confirm the details of the job and related compensation package. Much can be promised verbally, especially if a company is eager to have the candidate join the team. But promises not confirmed in writing may be forgotten once the employee is on the payroll, leading to frustration and bad feelings on both sides. You might think that your company is not big enough to require such formality.
