Purpose: At Impinj, we are committed to using technology to improve our processes while maintaining the highest standards of integrity and fairness. This policy outlines the permitted uses of artificial intelligence (AI) in our recruitment process for both candidates and our hiring teams.

How Impinj's Recruiting team uses AI:
1.    Interview Scheduling: AI-powered scheduling tools may be used to coordinate interview times between candidates and interviewers. This ensures a more efficient and convenient scheduling process for all parties involved.
2.    Skill Assessments: AI-based assessments may be used to evaluate specific skills relevant to the job. These assessments are designed to provide an objective measure of a candidate's abilities. Results from AI assessments will be considered alongside other evaluation methods to ensure a comprehensive review of each candidate.
3.    Interview transcription: With a candidate’s verbal consent, we may use AI to transcribe and summarize our interviews to reduce reliance on manual notetaking during an interview.

Candidate Expectations:
•    Preparation: We encourage candidates to use available resources for preparation. This includes conducting online research, engaging with professional networks, and asking clarifying questions.
•    Live Interviews: Candidates may not use AI to supplement their performance during live interviews, complete take-home assignments, or for sample work submissions, unless explicitly instructed or agreed upon by a member of the Impinj Recruiting team prior to the live interview or otherwise in advance of the assignment. We want to see your independent ability to think and perform. 

Impinj reserves the right to disqualify candidates based on the necessary skills and qualifications for the role(s) in which they’ve applied. If a candidate is reasonably suspected to be using AI during without pre-approval by a member of the Impinj Recruiting team, the candidate may be invalidated for the role.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
