    1. Why Build an Internship Program

    Before investing time and resources, understand the strategic value internships bring to your organization.

    The ROI Case

    Companies with structured internship programs report:

    • 50% faster time-to-productivity
    • Significant reduction in bad hire risk

    2. Defining Your Program Goals

    Start with clear objectives that align with business needs.

    Without structure, expectations are unclear and evaluation is hard.

    Delayed conversion decisions

    Top interns get other offers. Decide and extend offers early.

    Treating interns as cheap labor

    This mindset damages your brand and produces poor outcomes.
