it is 10 pm I hv interview for a job "given" by someone. Praise the lord, if I manage to go without getting too complex, that would lead to something unwanted.

If they're abstract, complex, if they're concrete I prefer simple.

I thrive when I know or at least sense a solution to them.

Complex human problems. Yes

I'm horrible with mechanics.

Yes I do. I am good at assessing and prioritizing issues in the order I need to solve them.
