3/10 – whiteboard coding, esp. with STL
This is one area my blogging is less effective

7/10 – syntax details — challenged only in one online test. Failed only on mostly stupid unrealistic context.

9/10 – internals, deep under, the drill-down WHYs

8/10 – comp science algo + data structure

– practical design?

Self-Rating is against my peers. Even if i'm 9/10 on something, I could come up against 2 candidates stronger than me, and I would then feel like 7/10.
