First week is half way through. Since I was well expected and I had a project, I had a computer and desk in an office with 3 others already set up for me. Bonus, my mentor is sitting here, along with the techlead of the project I am on.
Getting acclimatized to the setting of course will take a while. Organizational differences, new technology and a new commute will take a while to settle down. On the plus side, there is a strong educational orientation, with lots of documentation, tech talks, and friendly folks ready to help you out.
However my office is cold in the afternoons. East facing and all that. Brr.
