If a fast food company called you for an interview, is that a good sign that they will give you a job?

absolutely, I have worked in the restaurant biz for a number of years and I have ALWAYS gotten a job after they called for an interview.I'm not sure what the other comment was implying about no life but it doesn't matter what kind of job you are going for...dress well,good attitude and most importantly be at least 10 minutes early.Having an open availability will almost always guarantee a job.Good luck.Oh and make sure you thank them after and a firm handshake before and after.Hope I could help.Take care
