Strong recommendation from a frequent hirer: for each job, you should state what you accomplished, especially if that can be quantified. Supply the quantities! A list of what your responsibilities are is useless: did you actually do that stuff successfully?

For coding type jobs, I have found that relevant personal projects can also help. In the last interview I did a couple years ago, we spent most of the time discussing a relevant one and that was a good thing. When they ask a question like "What do you know about X?" and you can answer "I made an X and this is how it worked" it puts you in a good place.
