My first, major career position that I landed was with a small-sized company. Shortly after I was hired, the company was purchased by a very large corporation.
After acquisition, the parent company decided to let the smaller organization remain mostly autonomous but certain portions of the company were absorbed into the parent company. In my case, the Engineering department was absorbed into the corporate company.
Over the course of the next 7 years of my experience I, essentially, worked for the child company, however, by employment I transitioned back and forth between the two organizations on four separate occasions, for different positions.
I have done a lot of work after each transition but, at a glance, it looks like I've been job-hopping for over 10 years, especially considering that for the last three years, since I left the corporation, I've worked as a contractor.
My specific question is, should I consolidate all of my positions with the corporation, and it's subsidiary, on my resume for brevity and presentation? In such a case my CV will be quite sizable for that period of career because I worked on numerous project, all with diverse responsibilities and experiences that tend to be relevant.
I want to be honest on my resume, however I also want to construct it in a way that is readable and presents the most value that I can offer to a potential employer. I am a loyal person and if I were to find a good organization offering a full time position, I would gladly work for the same organization for another 7+ year run.
In such a context how can I, or should I, restructure my resume?
