Yap - many have not made it unfortunately. A combination of bad timing and/or crap at the interview/sim means they haven't nailed the interview. The reason why they're not posting here is they have drifted away. Don't under estimate the numbers. There are a lot who've fallen by the wayside.
The bad timing is worth bearing in mind. If you finish your training during a down town, then your IR skills degrade very quickly. Keeping your IR skills is very expensive.
