Multiple rounds with HR and business leaders to check not just domain capabilities but also cultural fitment. No of rounds vary depending on the position and the entity you have applied for.

I had a phone interview with a Honeywell Recruiter. At the end of the interview the recruiter told me that she was very impressed with my background and was going to set up a time within the week to interview with the manager. Well it has been over 2 weeks, I have followed up 3 times and have never received a response. I was very excited for this opportunity. I understand recruiting efforts can change, however to blatantly ignore my emails and not give me an answer or response is extremely unprofessional.
