I was given a take home assignment that takes approx 60 hours of unpaid time. Two weeks after the assignment submission I got scheduled for a 3 hours remote video interview with 5 interviewers. When I asked, I was told they would rather do a remote video interview instead of an "onsite" for candidates they are keen on (probably to save money). The video interviews were straight forward and mostly behavior questions. I was asked multiple time during the process if $130 000 (Total Compensation) would be something I would consider as a salary compensation. To which I answered, it ain't that competitive for a 5 years experienced engineer. Eventually I wasn't offered anything. The outcome was very surprising, I received positive feedback along the way from the external recruiter. I was told I did very well in the assignment and that the code was high quality. I did indeed put my heart and soul in to this test. They liked the fact that I spent extra time making documents and diagrams to explains the rational behind my design. One would think, if he spends, an unpaid, 60 hours on an interview process at least he'd been given a rejection reason or at least an assignment correction. Nothing. 60 hours just gone in the wind. Given the amount of time and extra care I put in to this, my conclusion is that they are super super super super picky with nothing to show for in reward. It ain't worth the risk given the reward. The take home test is a nice idea, but your time is best invested doing problem solving exercises and prepping for the traditional tech interview.
