> I would hate to see my team work on evenings and weekends

I've worked at startups and Google. The glacial pace of the latter can mean working late feels necessary to get anything done. And even tiny changes can take forever so the feeling of having accomplished something of value is infrequent at best. Maybe it gets better at higher levels, though the internal memes don't give me much hope.

Some people are suited to big corps while others prefer start-ups. Nothing wrong with a little diversity.
