PHP Methodology Interview Questions
Questions to ask a PHP Developer
PHP engineers are often required to have a knowledge of the full web stack: starting with the ability to write optimized SQL queries, and wrapping up with a good understanding of HTML/CSS. When interviewing a PHP developer, make sure that you think through your requirements and ask good questions for all of them.
Here's a suggestion for a good menu of PHP interview questions:
- Start off with some basic SQL such as SQL Skills: Joins, Averages and Sums
- Include at least one simple coding task such as Separate a list of integers or Find the missing number
- Explore their ability to come up with an overall system design and data model with a flexible question like Design a restaurant reservation system or Design a card game system
- Ensure that they have a solid understanding of the basic building blocks of the web by asking about HTTP GET and POST or What are HTTP cookies?
- Wrap up with some CSS questions like Explore the HTML display and position attributes or CSS rule-set basics
