I wonder if this has to do with your personality, how you behave under pressure, and how you react to not knowing the answer to something.<p>You seem more than capable enough to get a good job but in my experience, interviewers are looking to see how you react to being stumped.  If it&#x27;s anger&#x2F;frustration&#x2F;clamming up then that&#x27;s a turn off for a lot of employers.  They&#x27;re looking for more than the right answer.
