Upon arrival they make you read a story called "A letter to Garcia" after which the HR personnel will take you on a small tour with a brief over view of the organization and then do a short interview with you prior to the hiring manager interviewing you. Since I knew the hiring manager directly my interview was a bit different, it was approximately 2 hours and it was interrupted by the Senior VP last minute so that threw me for a loop.
I was extremely disappointed with the process, no one got back to me, no word or response, not even when I had originally applied and I had to go through my connections to have my resume delivered directly to the hiring manager.
I was also very disappointed with the way HR handled the end, after I had sent emails out asking about the status was I called back to let me know that they had gone with a different candidate. I believed them, only to be outreached by a recruiter for the same position! It would have just been nicer if they had been honest and upfront that they are looking for something different.
