Yes, you can! Just avoid super bulky items.
You can enter the building with your laptop. You will have to leave your electronic items with the security before entering the interview area.
It is advisable to just bring your document file/ folder with you. I have seen parents with kids with bags for kids stuff though. The security person usually checks the bags for items and lets you in with bags in case you have children.
I was not allowed to take it in. Had to give to my friend.
