Interview Process

The candidate received an initial phone interview. The interview focused on a coding question related to string tokenization.

Technical Questions

  1. Tokenize String (String Manipulation, Regular Expressions)
    Write a function that tokenizes a given string into a list of tokens. The function should handle the following cases:

    • Words separated by spaces.
    • Punctuation marks should be treated as separate tokens.
    • All letters should be converted to lowercase.
    • If the input string is empty, return an empty list.

    Example test cases:

    • Input: “Hello, world!”
      Output: [“hello”, “,”, “world”, “!”]
    • Input: " The quick brown fox jumps ."
      Output: [“the”, “quick”, “brown”, “fox”, “jumps”, “.”]

Tips & Insights
