PayPal Software Engineer II interview questions

I am referred by an employee and got a call from project manager regarding interest and general questions. Later a telephonic interview which is stressed much on heaps. Then called onsite for 5 interviews which are mostly on heaps, arrays, hash maps, restful design, java basics, some backend design and a tree question. A decent coder can crack the interview which is not at all difficult. Later a Skype interview with hiring manager led to an offer.

Initially contacted by the manager. Had a small conversation with the manager and then initial technical phone interview. Basic java questions were asked. The second round was 6 interviews 45 mins each. Questions mainly focused on core java concepts, design pattern and web services. Also, at Paypal, they give importance for enthusiasm and interests shown by the candidate.
