Hi, I'm also interested in SSP and SPS. Your decision sounds like a really tough one. Would love to hear what you ended up doing, and how things are for you?
Hi, I'm also interested in the MIPP program. Just following up to see how everything worked out for you.
I believe the requirement is fairly strict - and that those accepted tend to have more experience than the average. I think the total application package is what matters, and fewer years in a certain role/capacity may be more appealing to them (from an admissions pov) than a far longer career spent in a less compelling role.
