Great, had to bust out my thesaurus to look up sesquipedalian. My issue is the overuse of utilize instead of use. Then in writing classes they tell you not to overuse any specific word but to use similar words that mean the same so the text does not get too repetitive. But, if you are trying to do a resume/profile/cover letter, as Anne stated, you do have to use the buzz words in the announcement or position description.
