When you write CV you usually want to include some essential thing about your current/previous job, right?
The was some problems the last time I went to an interview for programmer position.
I included a line in the what-I-do-in-my-last-job part like this:
Deliver X revenue report
They asked about it. I revealed there is a system in our company to send some mass mail semi-automatically to other parties. I didn't write that system, however, I use it and maintain it(True, I've dig into the code base for some changes). All in all, it occur to them that I just use this system rather than developing it. I've use the right word - deliver but not create. They kinda LOL in front of me.
If the experience of maintenance is not important, I wonder why it is humiliating to include it in the CV.
