They ask you to travel to thier headquarters promisimg to reimburse for any expenses. For me, this was a several hour drive requiring me to spend the whole day in this process. The interview was fairly standard fair. I thought I got along well with the interviewers, as there are several. One if the interviewers showed me around the office. The problem was the lack of communication afterwards. I received no further communication. Nothing about reimbursement or the position. I had tried to follow up several times with no result. It was a black hole of information. This was years ago now but if this is how they treat interviewees, when they are supposed to be showcasing the company, then I guess I'm glad I never accepted a position there.
