I am in the process of updating my resume. It is not the most fun part of the job-search process because it is in essence a sales gig, not my favorite vocation. I have to go through the vast array of work I have done, distill the parts that are relevant to the job I am applying for, and condense all to one page in such a way that the reviewer finds it attractive to call me for the interview; that's the only goal of the resume, to get an interview.
I have reviewed other peoples' resumes and conducted resume writing seminars as a volunteer (for refugees to be specific) but critiquing myself is not the same as critiquing others; it is much harder.
I am not sure what I want to convey in my resume? Unlike many jobs, my title gives away most of what I do. So the goal is not to dwell on the "mundanes" but on "specific" achievements that are attributable to me. That's much harder because I work as a part of a team so I do not have ownership of anything. Anyway, I will have exaggerate something. May be I have to take the advise I used to give when I was volunteering; exaggerate but do not lie.
