Pros

The people I worked with at Illumio were truly fantastic — smart, supportive, and highly collaborative. The team culture at the peer level was one of the best parts of my experience.

Cons

Unfortunately, the management structure was very top-down. Leadership often felt out of touch with the realities of day-to-day work, and most major decisions were driven by the need to copy other products that were already on the market. This created a bottleneck for progress and made it difficult for teams to feel empowered or trusted to innovate. Despite the talent and dedication of the design and engineering groups, the lack of autonomy and over-centralized direction often stalled momentum and limited creativity. If Illumio can find a way to empower its teams and shift toward a more trust-driven, bottom-up culture, it could be an incredible place to work.

Hello and thanks such much for joining us for your internship this past summer! I'm so glad you enjoyed the people and the projects you worked on here. And thanks also for the feedback about the area of opportunity you saw around, well, feedback :). We'll take that input on board as we start to kick off the 2026 intern season (hard to believe it will be here before we know it!). Wishing you all the best this semester and looking forward to keeping in touch! Thanks, David Chief People Officer
