Surprisingly, this was one of the top recruiters in my country. Never knew, MNCs can be so so inefficient for such simple tasks.
Start-ups are way better in this regard. Latest tech, small community, minimal bureaucracy and a lot of respect and things to learn.

Observed a full deployment the other day and discovered it's extremely inefficient. I proposed an idea to fix it, and was shot down by a senior dev on the team. I was ranting about how asinine the process was and how my process could reduce the amount of time and training required to do deployments with out any additional cost or overhead. A senior dev from another department over heard me, found my workspace and told me (in a nutshell), "write up a document about why the current process is garbage and how yours is better, and how it works, I'll review it and we'll get it worded and formatted right. When we finish the document, I'll forward it to the CTO of your department with your name on it and my recommendation for review." Fuck yeah. 😈😎

So after waiting 3 days for an ID to get into a computer, I'm now told it's going to take 12-14 hours before I can do online security training just so I can actually start working. I'm only at this job for a month and I'm not going to even touch any real work at this rate...

Oh well, at least I'm paid by the hour, not by the amount of work
