They will contact you to prepare a case. You have 24h to prepare it and when it's done you are invited to a series of interview with couple of senior managers. The interview are relatively casual and they will ask you question about your personality, background and vision of the company, when you can ask as many question as you want: work, development, cadence, benefit, compensation, pretty much everything. Once you have met all of them then you can present your case and they will comment on it at the end asking you question on why you take such and such decision, assumption and they challenge not only the case but your aptitude to answer live in front of an executive committee. If everything goes well then you get the job.
