I did a tedious take home assignment while employed for a different famous company - it was clear they hadn't updated the instructions (broken links, outdated documentation, changed behavior). They gave this to me with a 72hr turn around requirement on a Monday morning (which I found a little thoughtless) I got a basic implementation working with reasonable code quality (not just hacked together) which took a few hours and then got turned down with no details. In general this is worse than a regular phone screen when the instructions are bad and it's not really clear what they're looking for.
