This is part of Adweek’s series covering fellowship programs at agencies. As agencies continue to face a talent crunch, many recent graduates or career changers are seeking a way into the industry. Here, we cover programs for entry-level marketers at top agencies.

The creative production agency Hook’s semester-long Sandbox U program offers one-on-one virtual mentorship opportunities for undergraduate students. The agency also has a year-long partnership with Los Angeles-based Hamilton High School’s Communication Arts Academy.

Hook’s undergraduate cohorts are comprised of 10 students, whereas the larger high school program welcomes 50.


Hook has a history of supporting mentorship programs, formalizing it with Sandbox U’s 2020 launch. It’s an unpaid program and doesn’t promise students a job upon their college graduation, but it does pair them up with mentors that can help them develop a creative portfolio and navigate future hiring processes.

To execute a separate program for high school students, it partners with Leila Lujan, an Alexander Hamilton High School faculty member who oversees the Sandbox program at the school’s Communication Arts Academy. Sophomores enrolled in an introductory design class and senior ad design capstone class need not apply for the program, since Hook partners directly with Hamilton High faculty and admits them automatically.

“I actually have students that say, ‘Oh, I can do this as a career. I can start to pursue this potentially after high school,'” said Lujan.

Raniah Al-Obaidi, a former mentee and current Hook designer, was a student at the Savannah College of Art and Design when she applied to Sandbox U. She joined the undergraduate program because she sought mentorship. The agency paired her with its executive director of design, who worked with her on internal education projects like a Kettle Chips rebranding initiative. 

“Having the ability to design something that was outside of school was really important to me because I wanted to see where my creativity could go,” she told Adweek. “I graduated this year and I was able to get a job at Hook because of the mentorship program two years ago,” Al-Obaidi said.

Hook encourages interested undergraduate students to apply and has eschewed its portfolio and resume requirements. “It’s more based on the passion, and we have some questions for everyone to answer,” said Alexandra Blum, people operations manager at Hook.
