Nobody gets on Intelligence or similar powerful committee first time at bat. I think everybody gets a committee assignment or two. Newcomers may get on some crap committee that doesn't meet much or introduce many bills. There are plenty of things a new Rep can do that doesn't require a committee assignment, like network and help build a caucus. Talent will out. If she is House material, people will notice what she's doing.
They can also do things in their own district and get in the press for good stuff.
