Is it a good idea to use Interfolio service for tenure track applications?
Speaking as someone running a faculty search committee, I doubt we'd even notice, as long as your application materials and recommendation letters are properly entered into our own application system.

On the other hand, many faculty recruiting processes (including mine) only request recommendation letters after applications have passed the first round of reviewing.  In that case, I would be a little suspicious of an application that suggested using fdje28dn@interfolio.com instead of name@mit.edu to request a letter from a well-known professor at MIT.
