6 rounds of interviews over about 2 months, with added, unplanned interviews along the way, focusing on getting strategic advice and a solution to a technical challenge they were having. Ghosted, until I reached out again and then was told that it came down to a final round and I wasn't selected. It has come to my attention that they never hired for this position. Looks like they were looking for free consulting after all. I would caution anyone looking to apply here.
