I applied online and got reply after one month. Had three rounds of interview. All telephonic. First interview was with the technical manager of the team. She asked me about my projects and other behavioral questions like why do want work at PayPal etc. It lasted hardly for 20 mins. Then the second round and third rounds were with the engineers within the team. They also asked me mostly about my projects. These were a bit detailed interviews and drilled down into the specifics about it.
