I agree with you that a lot of skill is transferable between technologies, but I suspect that some recruiters or hiring managers either don't realize that or they typecast you into a specific role. Resumes are a form of writing where being concise is better than being complete. Also, I should have been more clear. I don't erase everything about a past experience if it's a different technology. Here are a couple hypothetical examples to help clarify. In this first version of a resume snippet, the applicant should be applying for a Java position since it's filled with terms that make sense to the Java community: > Software Enginer at XXX Company > * I led the design and implementation of XXX Company's internal payment processing service which processes $YYY million USD in annual revenue. The project used Java, Spring, Hibernate, and MySQL. > * Introduced testing (JUnit and Mockito) into the engineering culture by leading brown bag talks. Increased unit test coverage on critical company projects from 0% to 73% over 2 years. > * Used JNI to integrate critical path code with XXX Company's proprietary hardware driver, increasing average performance by 8x. Here is a snippet representing the same experience, but catered toward a Node.js position. References to enterprise Java are removed, and the last bullet is replaced with a more relevant bullet: > Software Enginer at XXX Company > * I led the design and implementation of XXX Company's internal payment processing service which processes $YYY million USD in annual revenue. > * Introduced testing into the engineering culture by leading brown bag talks. Increased unit test coverage on critical company projects from 0% to 73% over 2 years. > * During XXX Company's annual hackathon, I implemented and presented a functional prototype service to present payment information in real-time using WebSockets. Now these changes alone are likely not sufficient to get a call back from the Node.js job position, but it changes the automatic typecast from "experienced Java developer" to "experienced developer" Hopefully this candidate has some other past experience in Node.js/web development/JavaScript to flush out the story.
