I got certified as CISSP this week. The preparation was grueling. So much material to cover. The exam itself was fair, but the test questions in the beginning were really weird. I was at first a bit taken a back but then onve the 25 test questions were out of the way it was smooth sailing. 125 questions and I was done.
It is a bit of a shame as I started working as a Data Scientist. The CISSP will probably just gather dust.
