Tata Consultancy Services Assistant Systems Engineer Trainee interview questions

During the interview, I was also asked detailed questions around the SDLC (Software Development Life Cycle) — including each phase, what activities happen, how documentation and testing fit into the cycle, and how change requests / production issues are handled across stages. They went deep into: Requirements gathering & analysis Design approach (High Level + Low Level) Development practices / coding standards Testing phases (unit, integration, UAT) Deployment strategy Post-production support and maintenance So they mainly wanted to evaluate how clearly I understand the end-to-end SDLC flow in real projects.
