It really, really depends on the teams you're on. I was at Amazon for four years and enjoyed my time there. I had one stint on a high profile high-pressure team that lasted about 6 months (no on-call, though). That was the busiest time I had at Amazon but it was kinda known going into that project. I generally worked 45-50 hour weeks, with the occasional 50-60 hour weeks but that was pretty rare. It's a big company. It really depends a lot on your manager, your team, and your org.
