I hate working with pretentious jerks. At first you might hope it's a show to see how you react. But typically they really do have serious mental problems.

Usually they aren't that talented, and have designed some system with ridiculous limitations. And they want to protect themselves from having the new guy come in and point out an obvious improvement.

The best thing you can do is ignore them, because it infuriates them. I personally like playing the "I'm oblivious to your attitude" card. It's especially fun to do after they rant excessively about some tiny little bug as if the world were coming to an end. Follow up with a pleasantry and a smile, and they blow up.

i can picture how every thing went down. when you get hired be careful don't be to aggressive or people with aliences will gang you.

saying the thing was easy was aggressive. you could have used different works.
work is normally 40% work 60% drama. when working with women it 20%:80%.

he should have said that he thought the test was well layed out. the test was a good way to test ones skill.

most likely the guy that was interviewing you did not know crap about programing so that why he told some one from the programing team to try and test you.(normally they just ask you questions)

and you insulted him in font of the boss. well good thing you said you did not mean it in that way. however that did not fix any thing. thats just going to make him try underground to get you back.

if i was you when i i got the job i would make friends with the fat guy to point the focus some where else.

edit:

people don't like to say thing when people that know better are around. if he tried to wig something you and the fat guy would gang him.

when i say gang im talking about make some one look like a fool (belittle them)

That fat guy would probably just smerk and and a joke with you behide the boss's back(he would not correct him and make the boss look dumb)

how ever base on nonnus29 reaction to the hows the test question.

i think nonnus29 would have corrected him if the guy said something wrong.

and that would make the boss look dumb in-front of his employ.

if nonnus29 did correct him the boss would play it off one of 2 ways depending on his personalty.

one would be to make roles apparent by saying something like: "Thats why you guys take care of the programing and i take care of the businesses work."

you guys should get the idea.

That's also know as cannabis second effect.
