Yep, you'r 100% right, it reminds me I once read that of all given jobs offers, 50% would be taken by someone who got introduced internally. Out of personal exeperience as employer, that so was decided by me because it was filling the need instantly. And out of those personal experiences, bad employees brought bad recruits, good employees brought good recruits. Unknown recruits? half good, half bad. Ironically chiraldic.
