ZTE Project Assistant interview questions

two rounds. First round was with 2 project managers. They are both very nice, and clearly interested to me. Asked me genral questions about my past expriences and why i want the job. The second round was with the head of london office, he talked to me less than 5 minutes and kept asking about my visa situation. Was a waste of time, if you consider my situation is not acceptable then why asked me back for the second interview. Their office is quite far, took me 2 hours return trip. Never heard from them again, disspointed .
