Technical Skills

1. Can you write a function to determine if a string is a palindrome?

This question tests your understanding of string manipulation and algorithmic thinking.

How to Answer

Explain your thought process clearly while writing the code. Discuss how you would handle edge cases, such as ignoring spaces or punctuation.

Example

“I would iterate through the string from both ends towards the center, comparing characters. If they are not equal, I would return false. If I reach the center without mismatches, I would return true.”

2. How would you implement a simple object-oriented design for a game?

This question evaluates your grasp of object-oriented programming principles.

How to Answer

Discuss the key components of your design, such as classes, inheritance, and encapsulation. Be prepared to explain your choices.

Example

“I would create a base class called GameObject with properties like position and velocity. Then, I would derive classes like Player and Enemy from it, each with their own specific behaviors.”

3. Given a specific filesystem, how would you show the dependencies of the files in the system?

This question assesses your understanding of data structures and algorithms.

How to Answer

Outline your approach to represent the filesystem and how you would traverse it to find dependencies.

4. Describe how you would design a database schema for a merchant transaction.

This question tests your database design skills and understanding of relational databases.

How to Answer

Discuss the entities involved in a transaction and how they relate to each other. Mention normalization and indexing.

5. How do you test your code?

This question evaluates your approach to software quality and testing methodologies.

How to Answer

Explain the types of testing you perform and the tools you use to ensure code quality.
