Interview Prompt
An engineer cleaning raw fields from an upstream export needs `safe_cast` to convert `value` to the type `type_name` names. The supported targets are 'int', 'float' and 'bool'.
Summary
Type conversion is easy, until it is not.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
