Autocomplete Rule - Default Fields Base on Job

Summary:

I am new to creating an autocomplete rule, my cases have been approve but I am not sure how to create the rule logic.

One of the rules I am trying to create is to have some fields default base on what their job title is.

Content (required):

When admin change employee's job title, fields should auto populate after tab out or clicking out of job title. Hourly Paid or Salaried should default base on Overtime Status from Job Details in Workforce Structure.

If employee's new job is exempt, Hourly Paid or Salaried should default to Salaried. If it is nonexempt, Hourly Paid or Salaried should default to Hourly.
