    | Scraped Title (Input) | Standardized Title (Output) |
    |------------------------|------------------------------|
    | Sr. Software Eng | Software Engineer |
    | Registered Nurse - ICU | Registered Nurse |
    | Accountant III | Accountant |
    | Sales Rep (B2B) | Sales Representative |
    | Elementary School Teacher - 3rd Grade | Elementary School Teacher |
    | Exec. Chef | Executive Chef |
    | Marketing Coordinator/Specialist | Marketing Specialist |
