I am out of state, so I started with several phone interviews, then they flew me down for an all-day interview with 7 people. They tell you ahead of time that there will be behavioral questions and that is indeed how the interviews were structured. Prepare for that and you'll do well. People were very professional and well organized I thought. I was impressed after my visit (which was in mid-December). It's now February and I haven't heard back and my two e-mails to my HR contact were not replied to. I feel this is very unprofessional and discourteous. I'm assuming the job is on hold, other candidates are being interviewed, etc., but at this point I wouldn't be interested in a job at GP due to the way they've handled the process. Respectful communication should occur between both the candidate and the interviewing company. At least a reply e-mail saying something to the effect of "stay tuned", or "we're not interested". Frankly I expected more from a Koch company.
