Your work ensures that clients can secure their crown-jewel applications without risking operational downtime.

• Structure your behavioral answers: Use the STAR method (Situation, Task, Action, Result) to keep your answers concise and impactful, focusing heavily on your actions and the positive outcomes for the client.

• Showcase your consultative mindset: In technical scenarios, always ask clarifying questions before proposing a solution. This demonstrates to the interviewers that you prioritize understanding a client's unique business context before making technical recommendations.
