It can be. I often find it "bursty." I've had months at a time when I had stand-ups and then "do whatever you want" for the rest of the day. I generally did do useful work, but there were plently of days when I was just chilling out.

Ive also had months where I ran from fire to fire while on fire, spreading even more fire. Also, there was fire.

It juat depends. If some org treats you as disposable, pays like shit and lights your hair on fire as you walk in, y'all should walk back out. The next org will probally treat you better, because there are good orgs out there. Even the good places get busy for a bit though. Just make sure that busy comes with money and that it ends at some point.
