When I started my first programming job, I felt like they didn't know what to do with me. This turned out to be a blessing in disguise. I used my time to study hard using their training programs that tracked my progress, and I ticked off as much progress as I could as fast as I could while making a good faith effort at in-depth learning.
I also was in daily contact with my boss.
I sent my boss daily email updates, citing my progress in the training programs and the other material I was studying and learning.
My understanding was that I would continue doing as I was until specifically assigned something.
I continued like this for nearly a month, and then I was assigned the responsibility of signing off on code and releasing it to staging and production. Having my MBA probably didn't hurt me in getting this responsibility, but I took it very seriously and leveraged it into further work with increasing levels of responsibility and opportunities for me to learn.
You are potentially in a similar position. You should take the initiative to make the absolute most of the resources available to you. If you can do it, and it is measured, do it. If you run out of measured activity, but you can find things that make you more valuable to them, do it. Starting off with the right strategy may make all the difference in your career. Good luck.
