When I got my Ph.D., I was at a crossroad. To work in academia, I'd need to do a post-doc for at least 5 years and try to get stuff impressively published. To work commercially, the usual track is to get an internship. That's the route I pursued. Because the work is high security, my internship addressed issues only related - while they saw my abilities and checked my security. The internship was to be for one year, but I was promoted after just 3 months (with my salary increased 3 fold). Nope, can't tell you what I do.... where I do it .... or for whom (even my wife knows WHERE I work but not what I do there). I love it since it is a very, very collaborative effort working with a very diverse team (from various backgrounds).... informal, friendly, supportive.... and challenging, demanding creativity and cooperation. I seem to "click" there very well - witnessed by a pretty big promotion even before my one year evaluation, a promotion recommended by my peers, my team.
I don't know what field your daughter works in, but I think often internships is the best way to "enter." They are the modern day form of a working interview, a lot of job offers flow from them. So much happens via the internet now, too. Most fields are VERY competitive but there are also counselors and courses that can help develop interview skills, etc. But I think it's STILL often a matter of who you know.... I got my internship is large part because the lab director I worked with in my grad years has strong connections with top people at my company.... his strong recommendation was my "ticket" - the internship was mine to loose (but I didn't). Of course, getting the internship and getting the job are not at all the same thing.
Best of luck to your daughter....
