Behavioral Questions
Tell me about a time you disagreed with a decision and how you handled it
Sample Answer (STAR Method)
Task: I believed a relational database would be more suitable given our need for complex transactions and data relationships.
Action: I scheduled a one-on-one meeting with the team lead and presented my concerns with specific examples of transaction requirements. I created a comparison document showing pros and cons of both approaches. I focused on the project's success rather than being right, and suggested we prototype both approaches with a small feature.
Result: After the prototype, the team agreed that a relational database better suited our needs. The team lead appreciated my data-driven approach and collaborative attitude. This taught me the importance of respectful disagreement and backing opinions with evidence.
How do you handle tight deadlines and pressure?
Sample Answer (STAR Method)
Task: I needed to manage my time effectively to complete everything without compromising quality.
Action: I started by listing all tasks and estimating time for each. I prioritized based on due dates and complexity, then created a detailed schedule with specific time blocks. I eliminated distractions by working in the library, used the Pomodoro Technique for focused coding sessions, and took strategic breaks to avoid burnout. When I realized one assignment was taking longer than expected, I reached out to the TA for clarification rather than spending hours debugging alone.
Result: I completed all assignments on time and performed well on my exams. This experience taught me the importance of planning, prioritization, and knowing when to seek help. I now proactively manage my schedule to avoid such situations, but I'm confident in my ability to perform under pressure when necessary.
