Continuous Learning and Growth

“When I joined ZS straight out of school, I never imagined it would become the only job I’d ever want.” That’s what Principal Kumar Ritwick had to say when reflecting on his career at ZS. Since joining the firm 15 years ago, he has mastered the nuances of managing client relationships and moved from Delhi to Boston, where he has lived ever since. “What’s kept me here isn’t just the role — it’s the constant evolution of the work itself,” Ritwick said.

“There’s always something new to learn and always great people to learn from.”

Currently, his team orchestrates integrated sales and marketing strategies for healthcare clients, a task that combines AI, strategy and creativity. “Integrating sales and marketing is crucial in healthcare because it’s not just about running campaigns — it’s about building intelligent, connected ecosystems that ensure doctors receive timely, relevant and consistent information when it matters most,” Ritwick said. While the work itself has positively shaped Ritwick’s experience at ZS, his coworkers are the reason why he has stayed at the firm for so long. “The culture here is one where I’ve consistently worked with people who are not only brilliant, but also kind, collaborative and endlessly supportive,” he said.

“I get to keep learning, whether it’s new technologies or new ways of working with clients, and I’m surrounded by people who genuinely want to help each other grow. Every project feels like an opportunity to make an impact on the client, the world and my team.”

Carolina Blanco, Business Technology Solutions Associate Consultant


The moment Blanco began her internship at ZS, she was immersed in real project work. “From the beginning, I was included in client-facing activities,” she said. “I had a great consultant on my team who pushed me to grow, always in a supportive way. He gave me space to lead calls and take on work I didn’t yet know how to do, then helped me learn it.” Blanco quickly built a strong foundation in consulting and gained the confidence to grow. Her current team works at the intersection of technology and client engagement with a focus on data engineering analysis, building tech solutions that make it easier for clients to find and understand important insights.
