I was recruited through LinkedIn. There was a bit of disjointedness as I was handed off to various recruiters and personnel throughout the process. There was an initial phone screening, then a video interview with 2 product designers, and then finally an on-site where I gave a presentation to several product designers, then had a whiteboarding session, followed by 2 1-on-1 interviews and then lunch with a designer. They were eager to set up each phase of the interview process but very slow to follow up. After my video interview it was 3 weeks before I heard that they wanted to move forward. Most frustratingly, after my on-site interview they never got in touch at all. So I assume they were not interested, but did not have the courtesy to even tell me so.

Straightforward like any big tech interview, but long and intense. Formats are pretty standardized so it just takes practice. Questions appear like it's from a bank, so if you're prepared you should be fine.
