PwC Senior Associate interview questions

The interview process consisted of two rounds. The first round was a screening interview that focused on my background, experience, and general fit for the role. The second round was a technical interview that focused entirely on system design. During the technical interview, I was asked to design a ticket booking system and discuss architectural decisions such as monolithic vs microservices architecture, modular monolith, scalability, and handling issues like idempotency and overselling. The interview was more of a discussion about design decisions and trade-offs rather than a traditional .NET interview that focuses on specific framework or coding questions.
