Efficient Input Validation with Regular Expressions in Google Forms

Have open openings in your company and want to create pre-interview questions using Google Forms? Using common fields like name, email, phone number, and zip code, you have created a form. But how can you be sure the data follows the right format before you deploy it? Is the data itself valid even if the format is correct? Are you considering implementing a CAPTCHA to prevent spam bots or a filter to remove vulgar language?
