Here are the most common types I faced:

Array Manipulation: Sorting, searching, or changing data inside arrays. These data manipulation tasks showed up a lot.

String Pattern Matching: Finding or changing patterns in strings. Sometimes I had to check if a word was a palindrome or count certain letters.

Dynamic Programming: Breaking big problems into smaller ones and solving each part. These algorithmic challenges tested my problem-solving skills.

Debugging Exercises: Finding and fixing errors in code. These questions checked if I could spot mistakes quickly.

System Design: Rare, but sometimes I had to think about how to build a simple system or explain my approach.
