Senior engineer is like a fuel efficient car - it's a meaningless marketing term used to distract attention from what matters - the pricetag and fuel consumption in hard numbers.

Are there ways to quantify the qualities of engineers, or any "human resource" in hard numbers? What are interesting qualities in particular?

Maybe salary, which is influenced by location as well as negotiation prowess and just plain chance.

Or maybe "experience", which is actually "years gainfully employed" and is at best a proxy for experience.

IQ could be a something to profile on. Which is a proxy for intelligence by measuring ability to recognize patterns.

Number of Github stars then? Which is really influenced more by marketing of the project than how good the code is.

Perhaps they have good stories or anecdotes. But that's not really a hard number.

Since one person can never be held liable to agree with another's definition of "seniority", it is just a subjective term.
