By implementing only that 1% of a real database's functionality that this task requires. Consider: you have only one table, no updates or deletes or transactions, fixed schema, and very, very simple queries.

So it's just a matter of parsing the CSV into some native data structure in your favorite language and then computing sort indices of the columns by which rows might be queried.

And sadly you don't even need to create sort indices. Just reading the data into a list of tuples and a few list comprehensions would provide all the querying needed (it wouldn't be efficient but most candidates can't even get that far)
