Aruba Networks Software Development Engineer interview questions

I applied through the career fair on campus. They contacted me after two weeks. First, the HR asked me if I could do a phone interview and then I was asked to drive to their site if possible. After I agreed, they decided to do a phone interview again. Before everything starts, the schedule already made me annoyed. Finally, my interview process began from a phone. And we made an appointment time, i wait there for a whole day, nobody called until I emailed them about this staff. What a terrible experience!
