I applied for a job opening last week, but now I don't want to. As I heard this company was bankrupted again. I want a stable job and so I don't want to.  I told them I had a thick sick and can not take the interview. But yesterday I got a call from them, they asked me some questions but not express their interesting. Today they called me again but I did not answered. I don't know what they will talk about. And I really don't want to go there. My friends said I can reject them because of weak health after sick. How do I?
