Simple, well organized, met with a lot of people from different teams. They were open and friendly, did ask some tough questions, but seemed to accept the responses. I would recommend negotiating (as per usual) though the recruiter I used encouraged me not to. Formal on-boarding is minimal should you decide to take an offer, so be prepared to guide your own journey in this regard. Meet as many people as possible at work and at company events. Their inclusive culture will assimilate you, you just need to make the first move.
