I just saw a fun “IT Personality Types” quiz, which touches on the types of geek one is likely to find. You can find the quiz here: https://www.infoworld.com/d/adventures-in-it/it-personality-quiz.
Personally, I think the types are not quite accurate and the quiz questions make more than a few assumptions. But reading through the various types is pretty amusing.
I found it via a more in-depth article on IT personality types at ITWorld.com.
I have my own breakdown of the various types of geeks you’re likely to encounter – and how to effectively manage them to your mutual benefit – in my book, Information Age Management and my book has the benefit of having comic illustrations drawn by the incredible Tom Bolger of SeeSpotClone.com
