Well that was short lived. Yesterday my boss sat me down and told me that I'm not right for the position. :( I'd been working there a week.
I guess I was too swept up in getting this job that I didn't take it seriously enough, but I also butted heads with my boss over 3D printing things (I fucking know this shit). I guess he also had a super high standard for what he expected, and in terms of sink or swim, I didn't swim fast enough.
This has been a real punch in the stomach, and kind of gotten me down, but I'm using it as determination to prove my worth. I'm currently in the process of setting up my own design and 3D printing business, and I can use them as a contact if need be.
As everyone has been telling me, when one door closes, another opens.
