For more than 27 years, PTP has operated as a premier Information Technology (IT) staffing, consulting, and recruiting firm—built on trust, long-term partnerships, and technical excellence. Based in the Chicago suburb of Park Ridge, IL, our team of more than 500 employees and consultants is dedicated to helping every client make the best hiring decisions possible. As part of that commitment, we believe in providing clear information about how our hiring technologies work and how your data is used. The following section outlines our AI-assisted interview process and your rights as a candidate. 

AI-Assisted Interview Experience (Pete & Gabi – Rebecca):

To provide a consistent, fair, and flexible experience for all candidates, we use AI-assisted tools—including our proprietary platform Pete & Gabi – Rebecca—to support parts of the interview process. These tools help us:

• transcribe interviews,
• summarize candidate responses,
• generate job-related insights
• streamline communication and scheduling.

Please note that

• AI does NOT make hiring decisions.
• All decisions are made by our human recruiters, hiring managers, or client partners.
• The AI does not evaluate facial expressions, emotions, or physical traits.
• It is used only to support fairness, consistency, and efficiency.

If you prefer a non-AI interview format, we will gladly provide an alternative.

Technical or Case Interviews (Role-Dependent):

For certain positions, you may participate in:

• a technical interview
• a coding challenge
• a case study
• a client-specific assessment.

We will always explain what to expect in advance so you can prepare with confidence.

Human Review & Selection:

Every candidate’s profile—including interviews, conversations, and assessments—is reviewed by experienced recruiters and hiring leaders.

AI insights may assist with organization and evaluation, but final decisions are always human-driven.

Your Rights as a Candidate

At PTP, every candidate has the right to:

• Request a non-AI interview path
• Ask how your data is being used
• Request access to transcripts or interview recordings
• Request deletion of your AI-recorded interview
• Receive clear, timely communication

Our goal is to ensure you feel respected, informed, and supported throughout your experience

Our Commitment:

For more than 27 years, PTP has focused on putting people first—candidates, consultants, employees, and clients.

We’re committed to a hiring process that is:

• transparent
• compliant
• equitable
• powered by innovative technology that enhances—not replaces—human judgment.
