Wells Fargo Sr. Software Engineer interview questions

I applied through linkedin. Around ten days after HR called me and scheduled the first round. One week later second round was scheduled. In between I did not received any feedback whether I was selected or not. approx 2 weeks later third round was scheduled.. Again i was not aware whether I have qualified my round or not.
