Nat_rodri- tell your wife to find another job, believe me the company cannot do anything. NOBODY can WASTA in this case!

Nathan- Stop waiting! if you can go back to your previous job, do it! while still have the chance. Its already 6 months. More than 3 wks of your application still no answer? forget it! they wont tell you're rejected or not, and wont even tell you what is the reasons?
