It probably depends what team you're on, but I would not describe it as "pretty shitty." Being oncall for a 24/7 service sucks, yeah, but for my team it is one week a quarter and I haven't had any outside-of-biz-hour alarms the last few shifts. Other than that -- my work is challenging and interesting, my colleagues are friendly and smart, and my manager is decent. Not a lot to complain about.
