This question aims to evaluate your technical expertise and problem-solving skills in real-world scenarios.

How to Answer

Discuss the specific algorithm you used, the context of the project, and the challenges you encountered. Highlight how you overcame these challenges and the impact of your solution.

Example

“In my last project, I implemented a Dijkstra algorithm for optimizing route planning in a logistics application. The main challenge was handling dynamic data inputs, which required real-time adjustments. I overcame this by integrating a caching mechanism that significantly reduced computation time, leading to a 30% improvement in response time.”

2. What programming languages are you most comfortable with, and how have you applied them in your previous roles?

This question assesses your technical proficiency and adaptability to different programming environments.

How to Answer

Mention the programming languages you are proficient in and provide examples of how you have used them in past projects, focusing on the outcomes.
