The problem is you're not going to have a solid understanding of your engineering role plan until you're employed, and even then, even with "preapproval" from the insurer, it might turn out you don't have the coverage you think you do.

My firm is in financial services. Very nice plan. Even with my "nice plan", we've had the insurer renege on their coverage of services (thousands of dollars in services) after receiving approval and having it in writing prior to obtaining services. YMMV.
