I have recently interviewed with PayPal for SSE role. It was a pool hire, not specific to any team. Below is my experience.

Round 1: This was a DSA round. I was asked below leetcode question with variation of it: https://leetcode.com/problems/steps-to-make-array-non-decreasing/description/

Round 2: This was a HLD round. I was asked to design a Web Crawler.

Round 3: This round was also a DSA round. I was asked only one question: https://leetcode.com/problems/zigzag-conversion/description/

The rounds were too frustrating and long. It almost took 4 months to complete 3 rounds. I feel like it was a waste of my time. Even all my rounds went well, they did not give any clear decision or feedback.
