Everyone I talked to at Novartis was nice and professional. Interviews were typically spontaneous and unrehearsed, but generally focused on relevant questions about prior experience and how I would solve particular problems.
However, the interview process dragged on for several months with no clear end or goal. Interviews were constantly cancelled and rescheduled. I lost at least 3 days work from cancelled interviews, and since I am a contractor, going through the whole process cost me over 1000e. The process ended with yet another interview that was cancelled at the last moment, followed by an email weeks later saying that I didn't get the job.
There are definitely some great people working at Novartis, but their behavior towards potential candidates is shocking and needs to be fixed.
