Use of AI Tools During Our Hiring Process:

At You.com, we're thoughtful about how we use AI throughout our business — including our hiring process.

During certain stages of the interview process, we may use AI-powered tools to assist with administrative tasks such as scheduling, note-taking, transcription, or summarizing interview discussions. These tools are intended to support our interviewers by improving accuracy and efficiency — they do not make hiring decisions or replace human judgment.

All employment decisions are made by our recruiting team and hiring managers based on a holistic review of each candidate and applicable evaluation criteria.

If AI-assisted note-taking or transcription may be used during your interview, we will notify you in advance. If you prefer not to participate in an interview that uses these tools, you may opt out by informing your recruiter before your scheduled interview. We will work with you to provide an alternative interview experience where reasonably practicable.

Information collected during the hiring process is handled in accordance with our Privacy Policy and applicable law. By continuing with the application process, you acknowledge that you have read this notice. If AI-assisted tools are used during your interview and you have not opted out after receiving notice, you consent to their use as described above, where permitted by applicable law.
