I had a referral, so I came by for lunch one day. I talked with a few people on the team - and then after a good chat, decided to do the take home problems. They were a good wide-range of problems that gave a me a decent idea of the areas I'd work on in my role. After a phone screen to talk through my take home answers - I was invited for an onsite. It was a few hours, meeting various people with more in- depth questions. Great to see the office and meet everyone. Was a bit long but I appreciated how thorough they were. Questions weren't boring.
