It is no big deal at all. People who did not know the difference between N1 and N2 got the job much earlier than me, some with multiple fails as well. Someone recently became a Captain despite having 7 fails. But he is a really good pilot and was/is an excellent instructor.
Of course, you need to know your stuff at the assessment. Got first time pass, zero fails, but nobody ever asked about them. So it makes no difference.
