It started with a couple of in depth phone interviews with talent hiring manager the nothing for a week or more. So I followed up and found that their "top" candidate got fed up with with the endless interviews with multiple individuals and withdrew. So now I'm the favorite, was tested, and then I was brought in for 6 F2F interviews and then a role playing Q&A with an in depth PP presentation. Fact is none of them faced the same scrutiny in their hiring. Even a cantaloupe would have difficulty pleasing that many hands. So they ended up hiring within to preserve the dis-function. Interesting that upper management of my previous company always labeled them as the most difficult partner and now I know why.

First round with HR, second round with hiring manager, questions are normal and standard and the hiring manager was very nice and third round there is a case study, all rounds are in Teams and remote format
