Problem Statement:

You are required to create a job-application form for hiring. The form collects the following details from applicants:

• Full Name
• Email Address
• Phone Number
• Desired Position (select from a list)
• Cover Letter

Your assignment involves the following tasks:

1. Input Validation:
• Full Name: Must not be empty; only letters and spaces.
• Email Address: Must be in a valid email format.
• Phone Number: Must be exactly 10 digits.
• Desired Position: Must be one of the provided options (e.g. “Frontend Developer”, “Backend Developer”, “UI/UX Designer”).
• Cover Letter: Must not exceed 500 characters.
2. Input Sanitization:
• Trim leading/trailing whitespace from all fields.
• Strip out any HTML tags or script characters.
3. Error Handling:
• Show real-time error messages next to each field if its value is invalid (e.g. “Phone must be 10 digits”).
• Prevent form submission until all fields pass validation.
4. Confirmation Message:
• When the user submits valid data, display a summary: for example “Thank you, [Sanitized Full Name], for applying to [Sanitized Position].
  We will reach out to you at [Sanitized Email] or [Sanitized Phone] shortly.
  Your cover letter: “[…]”
