Don't think about whether this is normal. Just ask yourself what you would like to be doing instead. Can you do that while barely doing any work at FAANG and collecting a paycheck? Or would you need to change jobs? I would personally wait until the recession has hit bottom before changing jobs. But then again you could get hit by a truck tomorrow.

I can tell you that lots of huge companies have this, but not consistently. Some teams move fast while some move glacially. Greenfield work can move the fastest, unless you get stuck waiting on someone to build environments.

Definitely don't stay there too long if you're unhappy. Worst case you try something new and it stinks, in which case you try again.
