I didn't see a thread so starting one.
I applied for these a few years back and recall having passed but not being called so hoping for a better run around this year.
I think my main stumbling block is the Situational test. Do people actually know what it is they are looking for in this? In the example questions provided, I can see merit in any of the answers - but that would all depend on the existing culture. I think it's somewhat biased to existing CS to know what the culture within a place is, as there is no obvious objectively correct answers.
