What I'm hoping folks get from the post is that not that many companies conduct algorithm interviews. If you're fine skipping FAANG, you can probably avoid them altogether.
Don't get me wrong, it was an excellent write up! Maybe my comment reads snarkier than I meant it :) My personal take away would be update my resume even if I'm not looking for a job. I've not interviewed for so long that my resume is written on papyrus and has qualifications like "knows how to tie his own shoes".
