A large part of the role involves research. Interns spend time analyzing markets, competitors, and customer segments to provide context for client strategies. This is not simple desk research. It requires structuring questions, sourcing credible data, and synthesizing findings into insights that explain why a market is moving in a certain direction. The ability to separate noise from signal is what makes this work critical, and interns quickly learn how to distinguish facts that shape strategy from information that distracts.
Once the research foundation is in place, interns often assist with strategic modeling. This can include market sizing, revenue forecasts, or impact assessments for new product launches. The intern’s role is to build reliable models, interpret outputs, and support the consulting team in deciding how a client should act. Accuracy matters, but so does clarity. The models interns create are designed not just to crunch numbers but to guide decisions that may involve millions in investments.
Presentation work is another major area. Interns contribute to the creation of decks and reports that clients actually see. This is more than formatting. It is about structuring a narrative that connects data, analysis, and recommendations in a way that clients can absorb quickly. An intern may spend hours refining slides to ensure every chart, bullet, and headline ties into the bigger story. This process teaches them how consultants distill complexity into simplicity, a skill that remains valuable long after the internship ends.
Interns are also embedded in the problem-solving culture at ZS. They join brainstorming sessions, contribute ideas, and see first-hand how senior consultants test assumptions, challenge data, and refine strategies. For an intern, these sessions are where they learn the consulting mindset: questioning everything, pushing for clarity, and structuring solutions under pressure. It is a crash course in how top consulting teams operate.
While direct client exposure varies, interns play a critical role in preparing for meetings, drafting briefing notes, or shaping the content that consultants present. In some cases, interns even sit in on client discussions, gaining a window into how professionals handle negotiations, objections, and strategic alignment. Even when they are not at the table, their work is woven into the materials that ZS delivers, meaning their fingerprints are on outcomes that matter.
If you want to move from understanding what interns do at ZS to experiencing it yourself, apply to their internship programs. They combine project exposure, skill-building, and professional growth in a way that prepares you for a consulting career.
