I can't vouch for it being worth the wait, but I can say how important it is to occupy yourself. I don't know how they're managing PAT now, but score the best long-term tasking that you can.
I'll pass the two years in mark shortly without an interview of any sort, but I've found my second wind in education. Look at the OPMEs, as they're taking applications for the upcoming semester and any bright spots on your MPRR is good. Check out CANFORGEN 037/11 as well, self-study second language is on it's way in. We'll just have to wait and see if it turns out.
Hell, I'm closer to being trained as a clerk than a Comm Rsch. I've gone from preparing for release to preparing for UTP-NCM. The requirements are strict, but if you have 2+ years of doing nothing, why not get some post-secondary education in? A brighter future has given me a second wind and I've seen far too many OT or release already.
Keep calm and carry on.
