You apply and get scheduled for a phone interview with the HR hiring manager. After you meet with the hiring manager of the department or group you will be working with. If you past that portion, you go through a 3-4 person panel where you talk with additional business units that work closely with your department.

Recruiter followed by Manager interview, waited 2 weeks, then had a full day, 6 hour marathon interview with 5 people followed by Recruiter followup. Waste of time, since they will lie at the end. I was told no offer due to reopening the listing for someone with more specialized experience, which is what my entire career is based on. It was made clear I had above and beyond the needed experience during the process but was asking for too much money. I was upfront with how much I wanted with the recruiter on the phone screen, but they still wasted my time going through the process and couldn't be honest in the end. They even sent me a virtual tour of the facility at the end prior to notice which made it all the more confusing.

Interview process was crazy long and ineffective. Too many rounds and tasks. Pulled out half way through as I didn't care about the job on offer enough. Strange vibes about the merger and culture
