Behavioral Questions
Give an example of when you had to make a difficult trade-off decision
Sample Answer (STAR Method)
Task: I needed to decide which feature to prioritize, as we only had time to properly implement one.
Action: I analyzed user feedback from our beta testers and found that 80% of users mentioned wanting notifications, while only 30% mentioned search filters. I presented data to the team showing that notifications would provide more value. I also proposed a simpler basic search that we could implement in 2 days, allowing us to deliver both features in limited form.
Result: We implemented full notification functionality and basic search. User satisfaction scores in our final presentation were 4.5/5. This taught me to make data-driven decisions focused on user needs, and to look for creative solutions that don't require choosing between extremes.
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.
