Popular, Inc. offers a paid summer internship for approximately eight weeks and is open to students who have completed at least their third year of a bachelor's degree; this program emphasizes full-time, project-based work experience. A semester-long internship option is also available, placing students within a single business unit for a longer period during the academic year.

Interns are generally placed within one of the company's core functional areas, including retail banking and customer service, commercial banking and business development, insurance and wealth management, consumer and mortgage lending, technology and operations, data and analytics, compliance and risk management, and finance and accounting. The program is positioned as a pathway into the financial services industry for students studying business, finance, technology, and related fields, with the summer and semester options structured to give participants direct exposure to a single team's work over an extended period rather than a broad rotation across departments.
