Telephone interview, using TitanPad. There are a number of functions you need to perform in Perl, such as palindrome detection, and a number of queries you need to perform in SQL.

There are other questions about the complexity of the functions you need to perform in Perl. There is a question that is a bit strange for a developer, in which you have to choose one of two business models.

You must choose one of the two business models as best:

• In model one, your company buys rooms in various hotels.
• In model two, your company is an intermediary.
