Interview Prompt

Implement a singly linked list class from scratch. It must support inserting a new value at the end of the list, and finding whether a value exists in the list. The class should expose an insert(val) method and a find(val) method that returns True or False.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
