I am writing my resume and have got one confusion regarding the tense to use when detailing present and previous job descriptions. I will ask my question with an example so that it is easy to understand what I am trying to ask.
I want to write "Understand and discuss requirements" as a bullet in the descriptions of both my present and past jobs.
Do I write it as: 1. "Understand and discuss requirements" OR 2. "Understanding and discussing requirements" OR 3. "Understood and discussed requirements"
Which of the above should go for the present job and which one for the past? I believe it would be the 3rd one for past jobs, but some confirmation would be good.
Any help is appreciated. Thank you.
