I've been trying to understand how my compensation stacks up against the competition. I understand that this can be a bit of a localized question, so I'll do my best to avoid local issues.
There are a number of web sites that provide salary survey data about different jobs. I've been looking at the data on careerbuilder.com in particular. I would like to use this data to understand how much salary I would be wise to ask for in negotiation, but it seems impossible to interpret.
However, when I go to the salary surveys on careerbuilder.com and enter in "computer programmer", "application developer", "web developer" and other seemingly similar titles, I get wildly divergent results.
Even more divergent are the results on Glassdoor.com, which reports survey results from individual companies. Consider this example: ( http://www.glassdoor.com/Salaries/net-salary-SRCH_KO0,3.htm ) that has differences of over 100% salary between different companies for the same title!
