Position provides tons of experience in the short term, but staying in position quickly plateaus in terms of any long term vouchability and career advancement. No decent HDHP options. Unless you are willing to downgrade to their health plan from day 1, reconsider. Understand that, rather than accepting your COBRA documentation and trying to help you, HR will try to throw you under the bus with a bunch of unnecessary nitpicking when you eventually do try to use their company plan.
