Tips on how to write a resume for web developer/engineer

I’ve been screening a lot of resumes these days to fill out one open position in our team. However, most of resumes that I reviewed writes about what projects were about and what role the candidate was on.

I rejected most of those resumes and sent back to recruiter.

Resume is a representation of you as an developer/engineer. As an engineer, don’t you want to discuss how you solve an puzzle instead of telling me what the puzzle was all about, what the rule the puzzle had, and so on?

I am looking for a resume that shows me how you solved an issue, how you improved performance, why you chose this approach over that approach, and so on.

In summary, I’d like to see more details on how and why you do.
