A Google SWE Intern interview involves:

• Coding challenges
• Data structures
• Algorithms
• Problem-solving questions

This is often conducted via online assessments and technical phone or video interviews, emphasizing clear communication and efficient solutions.

Coding Challenge: "Given a list of integers, write a function to find the maximum sum of a contiguous subarray using Kadane's algorithm."

Data Structures: "Explain how a hash table works and describe a scenario where it might cause performance issues. How would you address those issues?"

Algorithms: "Write a function to determine if a string has all unique characters without using any additional data structures."
