My question involves unemployment benefits for the state of: California

Well, I am getting close to my 99 weeks of unemployment. I received my first check after the senate passed the initial 60 votes a couple weeks ago. So I filled out my information, posted the jobs I was looking for in the back and filled out my entire UI document as always. So today I get a letter stating I have a phone interview. So I am wondering what this is about.. Is this random or what? it states some of the questions will be about

Being Physically healthy enough to take a job.
What type of work am I looking for?
Can I work right away?

So is this just to check up on me or what? Was I randomly picked for it? What else can I be looking for in the questions they may ask. Thanks in advance!
