Riverbed Technology interview questions

Campus career fair - on campus interview after. Had a group of people answer one interview question, and then line up for on-site code review. Key is to have a good resume.

Straightforward but very disappointed and frustrated. Why would you put me through 5 interviews in a 3 week span when you already have someone who applied earlier than me that you are about to hire? I feel like there was a lot of time wasted on my side when they already made up their mind they were going to hire someone else ! After all the rounds were over they were mentioning that tenure in my current org was less, was it nor visible at the start when they hand picked my resume to proceed further?? After wasting all the time , asking me to apply leave for a day to appear for the interview, at the end they came to see my tenure details? I mean was it true or it was just an excuse because they already had candidates inline and was trying me out? The worst part been after completing ALL the rounds the HR went mute on me and on asking for feedback twice he mentioned that the ENTIRE panel went on vacation for 2 weeks during the same duration, which was an excuse very difficult to buy and the best part been, that vacation never ended !!!
