We were meet in the morning and all of us were invited into the meeting room. First took a look at the PayPal's business. Then I was given a system design question just how to design a Vending Machine. He give us about 45 minutes to finish it. Then there are two round of interview. There are no much difference. One part is to review your code design and the other is to review your resume and project. The whole process is really enjoyable.
