The people. I find devs to be (obvious generalization) prone to: not take criticism, not understand the difference between fact and opinion, not understanding that it is perfectly acceptable to change your point of view when presented with new information that will conflict with what you currently believe in. It is a sausage fest brought to you by eons of very fragile male ego in the making, and many other qualities that were very much diluted in a lot of the other fields I have worked on: from retail (shitfest) to import/export all the way to military (another shitfest, for different and rather dangerous reasons).

I have met some amazing people in the field, don't get me wrong, but the quirkiest of mfkers i have met make me believe that maybe I AM the one that does not belong in the field (top kek).

On a more technical side, basic stuff like reading comprehension, attention to detail, the ability to translate complex problemd to pieces and that interconnect among the themselves, the ability to understand the grand mathematical scheme of things, the ability to be patient and despite what the above generalization would have you believe...the ability to communicate with other humans with tact and understanding as well as a spirit of collaboration, etc etc, are definitive traits to consider if you want a career in software development that leads above just being a code monkey.

Shit like that.
