ISTP + ENTJ

These personalities are quite different from each other. Their common preference is (T)hinking, which makes them direct, honest, consistent, and logical. They like to analyze issues and connect on an intellectual level.

ISTP's differ with ENTJ's in the way they interact with the world. ISTP's notice the details and solve problems on a step-by-step basis. ENTJ's are "big picture" people and zig zag from one idea to the next. ENTJ's find many ISTP's to be unimaginative. ISTP's find true ENTJ's to be overly demanding control freaks.

Conflicts mostly arise due to the (J) & (P) preferences. J's want order, a clean home, and are constantly seeking closure on issues. P's are more interested in processes, flexibility and keeping options open. It's the classic clash of the Odd Couple (Felix and Oscar).
