I'm interviewing for a job as a WordPress Developer. I've only been working with WP for a year now and feel I have a good overview, as in how to set it up, what functions.php does, where to modify themes, etc.. But the interview I have next week is going to be asking me all about WordPress and Linux with some MySql thrown in. All I know is that they will be giving me a laptop and a test.
How do I prepare for such a thing? Should I practice writing a plugin today? I know how to set up a Linux server, but I'm not great with advanced file manipulation or shell scripting. I'm good at setting up, troubleshooting and configuration. And I read the WP Codex a LOT. What would be a good homework assignment to give myself to prepare properly? I've noticed there aren't many resources for studying for a WP-centric interview out there.
