* For large employers you can no longer apply directly without an inside connection to hand carry your resume to the hiring manager and vouch for you. These large employers are required to post open positions online and accept applications online for EEO compliance but otherwise ignore all incoming resumes. They are receiving too many resumes online and so now ignore them out right.

* Third party recruiters are expensive for everyone. Yet, they can bypass the stupidity of the prior bullet point.

* Developers, in most cases, are a commodity. A meaningless replaceable gear in a larger machine. Talent and skills are largely irrelevant in many areas of software now, but years of experience still appear to be tie breakers. You resume should account for these considerations if you want to achieve employment.

* I am noticing lately hiring is walking back from that prior bullet point because commoditization of candidate selection does not work for more senior positions. For example you cannot substitute competence for a framework and cheaply achieve security, accessibility, test automation, architecture, and so forth. Eventually making decisions becomes more important than putting text on screen. In this case your only goal is to land an interview by any means possible so that your experience can do the talking.
