The interview consisted of questions on Object-Oriented Programming, PHP, SQL, and Linux commands. They primarily sought a candidate proficient in PHP and SQL, which I was not. I had previously edited some PHP content but had never developed anything. In SQL, I had taken a one-semester class, most of which I had already forgotten. The question session was conducted over the phone and lasted half an hour. Some of the questions included:

• Why does Java require "static" in the main function?
• What is a static function?
• What are outer and inner joins in SQL?
• Provide a SQL statement that returns the count of rows.
• How do you sort by/group by?
• What are sessions in PHP?
• What are double dollar signs ($$) in PHP?
• What are the following Linux commands: more, less, pipe, grep (also a problem involving grep)?
