Tips for Your Interview
Think out loud
Interviewers want to understand your reasoning process, not just your final answer. Narrate your thought process as you work through problems.
Ask clarifying questions
Before diving into a solution, make sure you understand the problem fully. Asking smart questions demonstrates thoughtfulness and attention to detail.
Use the STAR method for behavioral questions
Structure your answers with Situation, Task, Action, and Result to deliver clear, compelling stories about your experience.
Practice under realistic conditions
Simulate the interview environment as closely as possible. Set a timer, use a whiteboard or shared editor, and practice with someone else when you can.

Thoughtful questions about the team, culture, and technical challenges show genuine interest and help you evaluate if the role is right for you.
