did i srew up at this interview??

hey house i think i mite have srewed up big time.
i went for an interview,at the end i was asked if i had any questions for them and i said 'no'
moreso, i dont think i specifically thanked them after the interview,instead they apologised for keeping me for so late{actually,we were there till about 9pm or even 10.
did i srew up, cos i just read that not asking questions means u are nt interested in the organisation

Well, i don't think you screwed up. Even if you had questions.... haba...it was getting late for God's sakes. What kind of mechanical question would you ask?

u are asking if u screwed up...listen i think i screwed up more, i was askd wat salary i wldn't collect at all so they wldn't call me 4 it( a telecom company) and i said nothing less than 40,000. now tell me how bad can that be. am stil wonderin how i said that?
