I'm over 10 years out of college. Last time I implemented a linked list was probably in my second year of a CS degree.

I still remember and will probably never forget how to at least psuedo-code a linked list. But you are right, I have never implemented it after college.

However knowledge of pointers, lists and b-trees have been very helpful multiple times throughout my career.

Indeed. And such glorious moments they are when choosing the right data structure drastically improves performance.

However, if I were interviewing for a Rails developer position, the last thing I'd anticipate having to bone up on is algorithms and data-structures. I'd be expecting to be asked about... well, doing stuff in Ruby on Rails.
