I worked at a ~smallish startup. While we had around 20 devs employed we shared oncall between 3 people.

We invested a lot into availability - especially DBs. Most of our issues were internal DNS related which we at one point automated into hosts files that updated every hour.

Oncall was shared between 3 of us with all 3 paged at once and us getting on WhatsApp to 1. diagnose and 2. fix. Most of the time only 1 of us was close to a laptop but all 3 of us would assist as best we could.

One of us wasn't tethered at any point in time but for the most part we were able to get to a laptop within 30 minutes at most. I now work at FAAMG and find oncall especially stressful but it's once every ~6 weeks.

What is the on call like? Why is it stressful?

How many days/hours every 6 weeks? Is it 24 hours when you are at it, or only during the day time in your time zone?
