They had me meet with 12 different executives over a 5 month period. One executive didn't show up after rescheduling 4 times. I had to then follow up with the recruiter to be told that they decided to restructure the role and would not be proceeding further.

Call with HR followed by an in-person interview with the hiring manager. The interview was very congenial with probing, but fair questions. Next steps were defined. I did not receive a response and then a random HR person (very polite) called me to say they had gone with another candidate.
