Applied online through their Careers website. HR contacted me few weeks later and asked me if I was available to talk to a manager. The manager generally questioned me on my interests, projects and described at length about the projects at Paypal. He asked me a few questions on my projects and in general, my opinions on different languages, technologies. After this, I had a technical phone screen with one of the engineers on the team. It was a coding round coupled with some questions on OOPs, multi-threading etc. I was immediately contacted for another set of interviews. Since I could not go onsite to their SFO office, all these rounds were online. I had three interviews which were completely coding. But the interviews were really friendly and extremely cool. They would let you arrive to the solution and were interested in how you think ,your reasoning apart from your code.
