How to Answer

Discuss the definitions of both data structures, their use cases, and how they differ in terms of operations like insertion and deletion.

Example

“A stack is a Last In First Out (LIFO) structure, where the last element added is the first to be removed, making it ideal for scenarios like function call management. A queue, on the other hand, is a First In First Out (FIFO) structure, where the first element added is the first to be removed, which is useful for scheduling tasks.”

2. Describe a challenging bug you encountered in a project and how you resolved it.

This question assesses your problem-solving skills and resilience.

How to Answer

Provide a specific example, detailing the context, the steps you took to identify the bug, and how you ultimately resolved it.

Example

“In a recent project, I encountered a memory leak that caused the application to crash. I used profiling tools to identify the source of the leak, which was a forgotten reference in a data structure. After refactoring the code to properly manage memory, the issue was resolved, and performance improved significantly.”

3. How do you ensure the quality of your code?

Quality assurance is crucial in software development.

How to Answer

Discuss your approach to testing, code reviews, and best practices you follow to maintain high code quality.

Example

“I implement unit tests for all new features and use continuous integration tools to run these tests automatically. Additionally, I participate in code reviews to ensure adherence to coding standards and to catch potential issues early.”

4. What is your experience with cloud computing platforms?

Given the emphasis on cloud technologies at Broad Institute, this question is likely to arise.
