So, I had a job, finally! I was working on embedded Linux in a professional context for the first time, or so I thought.
After only 2 or 3 weeks, things started to get weird. His once amusing and on the same wavelength personality started to crumble. Cracks appeared here and there but I was too focused on my work to see them, or to even get worried, at least initially.
When he asked me to perform some reworking of the code repository and praised me for having thought of it before he asked me, then started shouting and swearing plenty at me to put it back the way it was because he hated what I had done, is when I first got suspicious.
But he said he was sorry for his over the top reaction, so I didn't think much of it after then. Not until it happened again, this time I kept arguing that having our system read-only would be a good thing to avoid data corruption. He would have none of it, and was extremely rude again.
