In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at RMS. The interview process will likely focus on your technical skills, particularly in algorithms, programming languages, and system design, as well as your ability to communicate complex ideas clearly. Be prepared to demonstrate your problem-solving abilities and your experience with software development practices.

Algorithms

1. Can you explain how you would approach solving the "Group Anagrams" problem?

This question tests your understanding of algorithms and data structures, particularly how to manipulate strings and use hash maps effectively.

How to Answer

Discuss your thought process for grouping anagrams, including how you would use a hash map to store sorted strings as keys and their corresponding anagrams as values.

Example

“I would first create a hash map where the key is the sorted version of the string, and the value is a list of strings that match that key. For each string in the input list, I would sort it and check if it exists in the hash map. If it does, I would append the original string to the list; if not, I would create a new entry.”

2. Describe how you would implement Polish Notation.

This question assesses your knowledge of data structures and algorithmic thinking, particularly with stack operations.

How to Answer

Explain the concept of Polish Notation and how you would use a stack to evaluate expressions.

Example

“To evaluate an expression in Polish Notation, I would use a stack. I would iterate through the expression from right to left, pushing operands onto the stack. When I encounter an operator, I would pop the required number of operands from the stack, perform the operation, and push the result back onto the stack.”

3. How would you approach the "Binary Tree Zigzag Level Order Traversal" problem?

This question evaluates your understanding of tree data structures and traversal algorithms.

How to Answer

Discuss how you would use a queue to perform level order traversal while keeping track of the current level's direction.

Example

“I would use a queue to perform a level order traversal of the binary tree. For each level, I would determine the direction of traversal (left to right or right to left) and store the values in a temporary list. After processing all nodes at the current level, I would add the temporary list to the final result.”

4. Can you explain how to design an in-memory file system?

This question tests your system design skills and understanding of file systems.

How to Answer

Outline the components of a file system and how you would implement them in memory, including data structures for files and directories.
