GE HealthCare Staff Software Engineer interview questions

The process started with a telephone call with the hiring manager to discuss the role and a bit about my experience. I was then given a 1 hour Skype panel interview with some of the team in the US. This was a pretty straightforward discussion about my experience. Finally there was a 1 hour F2F interview with the Hiring manager as well as a HR representative to discuss core competency questions. I was told this was mostly a formality but seems like I did not provide enough management buzzwords for their liking. Then the recruiter did not even have the professional courtesy reply back about my rejection, despite the company having stretched out the process to last over two months.
