Then I saved 45 minutes of my life, great. The point is, if you want to join the company I work for (and many people want to), you have to jump through the hoops of this company.

You should re-read the start of my comment, because I don't think those whiteboard questions are a great way to hire people. I just don't think there's a way that's more respectful of the candidate while being time efficient and providing good data points.

The truth is that the achievements that you claim can have been done by others. I'm in a top 1% company, and yet I see many people that are just utterly shit at being software engineers. There are parasites like this everywhere and they can just coast and claim the achievements of others for themselves (especially when applying to another company that has no way to verify their claims), so whiteboarding exercises and others crap is 100% necessary, no matter your level.
