Did you get annual COL or merit increases? The only companies I've worked for that didn't do annual reviews, also didn't give annual raises.
After megacorp release, I was invited in by a much smaller rival contractor, which was employee-owned. Mega had 100,000+ employees, while minicorp had 500+.
I've been through one year-end review at minicorp. It was very simple to do, as I had practice with the process. Many younger employees struggled with the self-review, just as I had in the beginning with megacorp. It was not too hard to pump up what little I had done in 3-4 months.
The company rules specified that I had not been there long enough to get a raise, so I really expected nothing. Manager went to another company. New manager was pressing me early on about more responsibility, and I was honest with him. Said I was looking for less, that I was not on a career path, just wanted to perform a job. Customer feedback was all positive.
One day I got a call from manager, who was in weekly meeting with executives. He asked me if I got a review or raise. I said no, explained what I knew, and I had submitted self-review. He said that something was wrong, and put me in for a raise. Later got 3%, which was more than all raises at megacorp, save one.
Not related, but minicorp missed my instruction to raise contribution enough to get the entire yearly match in just 3 months at year's end. I wrote to benefits admin, and he said I had actually done things correctly, but they missed the instruction. I received the entire match in my account, without any additional contributions on my part.
In this one case, there is significant difference in how raises are given out. I don't think ranking comes into play as much as with larger companies. For those who are truly bottom quintile, they wash out early. The workforce is also much younger, and competition exists for labor, from rivals.
