@3rpq You touched on some points I wasn't going to and I relived that nightmare job. I am the OP of the @3zsh post.
While I was the 'token white guy', I learned we were running with a skeleton crew. Barely a skeleton crew. I was in a support role and the Indian contracting company was so cheap and milking the contract that we had only 2 support shifts both being 12 hour+ days. One onshore and one off. I have always worked in a 3 shift 8-9 hour on-call rotation with overlap. (I did that schedule for 9 months because it took them 3 months to get me access to everything I needed to do my job. And there was no onboarding plan. My health deteriorated.)
It was on-call he-l. Everything the dev team handed over came with extra instructions because nothing the dev team installed worked as intended. And was never, ever fixed. So we had workarounds for literally everything.
The person I was replacing only lasted a year in the role I took. Same with the person before him. I later learned that I was the 3rd person to accept this role. The 2 before me bailed. I suspect they were tipped off about how bad the job was. That's probably why they offered a signing bonus.
