My manager called me in during orientation just like you mentioned...and all she wanted to do was to touch base and see how things were going. I was actually shocked that she was asking if there was anything she could do to help me and that if I ever needed anything her door was always open. I wasnt expecting anything crazy to happen, but its just a natural reaction to be unsure of yourself in this situation. My only 2 cents....if she thinks things are going well and better than expected or something along those lines, dont be afraid to stand up for yourself in terms of still needing/asking for help and having the orientation length you were lead to believe would happen. I know a lot of new grads who were told/promised one thing and given another. Management will not always look out for your best interest - that's your job.
