The salary data is interesting. But I found the clear example of title inflation quite shocking.

Promoted to "Senior" after only 1 years and 4 months. (Not counting their placement year here) and the "principal" in just under 4 years.

I have close to 20 years of experience this year so it kind of makes me chuckle when people with only a couple of years experience get refered to as senior. Admittedly, my title is equally laughably inflated, it seems to be a growing trend.

(This isn't intended to be personally disparaging to jvt. My comment is more on the state of the industries naming conventions)
