DuckDuckGo Senior Software Engineer interview questions

Multiple stages, 3 paid projects, some of them multiple days worth of work. Extremely long process, and you'll be rejected without feedback. There's a minimum word limit here apparently so let's work around this.

They say their process delivers significantly better results than the usual interview processes - and I believe them. They measure what you'll actually need on the job. No leetcode or artificial time pressure. But do expect it to be tough and thorough, requiring long periods of focused effort. It was about 3 months for me and included 4 interviews and 3 take home assignments, with rounds of feedback for each.
