You're making the assumption that being on-call made some kind of difference to your career progression--as other commenters have noted, no one is doing good or interesting work during on call hours. You're just the company bitch and you get to do bitch work. Other industries require hazing like this too: finance comes to mind. But not every software firm requires on-call; you just picked the wrong company and allowed yourself to get screwed.

As a manager, yes it did. Managers are simple people. All they do most of the time is try to figure out who is critical and who is expendable (invest or tolerate). While it's not the only path to the invest bucket, putting out a fire in the middle of the night is a quick way to land there. It's often a good way to prove yourself in early career scenarios when you don't have a ton of architectural pull power.

Two things.

1) I didn't just put in on-call overtime. I put in "free" hours in general.

2) I'm not really making a big assumption. Unsurprisingly working a lot of hours gave a very positive impression of me and I was able to easily justify raises and promotions when I asked.

Calling on-call hazing or bitch work is stupid, I'm not engaging with this.
