Technical Questions

  • Time Based Key-Value Store
    Implement a function get_when(self, timestamp: int, key: str, field: str, at_timestamp: int) -> int | None that returns the value of the specified field at the given timestamp from the record associated with the key. If at_timestamp is 0, perform the get operation as described in Level 1. It is guaranteed that at_timestamp will not be greater than timestamp. If the specified field or record did not exist at the given timestamp, return None.

Tips & Insights

Be prepared to write code in C++ during the interview, and ensure you are comfortable with the language, especially if you are more familiar with another language like Python.
