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.
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.
