I just posted a couple of months ago about me planning to conduct Unity workshop.
anyways,
why limit to the two engines? I'm a game developer but i dont use either Unreal or Unity, i write my own engine, but i know Unity, i use it for demo and teaching. I do things natively, coz it gives me full control and not binded with some sort of commercial paradigm and licenses.
what do you mean you are in the middle of a startup? you mean you have/own a startup company or youre working for one?
If you own or manage one, then hit me up, maybe i can help you,
and with regards to hiring fresh grad, there was a company in Cebu, Also a startup, Japanese managed, who started their own game studio, hired bunch of fresh grads without experience in software engineering in general, and failed in 3 months, by failed i mean they closed. Major reason aside from having 0 experience in game development, they have 0 experience in professional software engineering in general. There was no senior engineer/architect to guide them. (This case just happened recently)
