PayPal Senior Developer interview questions

After clearing technical telephonic I got called for an onsite. I was really surprised by the coding question they asked, it was just brute force question which doesn't require any knowledge and experience. I left after that without attending other 2 rounds.

I interviewed with Paypal Partner Integrations Team. Started with a recruiter call followed by phone screen conducted via the third party called Karat. The phone screen had 2 medium questions - leetcode level and those Karat engineers looked pretty talented and professional. My onsite experience was unfortunately very negative and insulting. It's not just about the lack of diversity but the major issue with knowledge base interacting with the employees in the Paypal Partners Integrations team. So they don't even know basic concepts like constant time complexity, code optimization, and performance techniques and basic data structures/algorithms. One of the interviewers at MTS level asked me a leetcode medium question which was a simple O(n) sliding window and solved it in 15 mins. I doubt he understood the terms like linear time, polynomial, exponential time complexity. Can you imagine what was his follow up question to sliding window problem? -> "Can you solve this by dp like creating a matrix". I was kind of amazed by his tech skill and then I cross-questioned him - " how can we solve this dp. Won't it be O(n^2) with this matrix? ". He answered, " Yes but with matrix, you can simply go diagonal and it will be cleaner and dp solutions can help in solving many complex problems without data structures". He had no idea what he was talking about because the diagonal solution by matrix was incorrect. I agree tech in the bay area is full of Indians but they are also very talented at the same time. I was surprised to see this poor demonstration of Paypal Partner Integrations team. After the interview, I looked up their LinkedIn profile and found that they were Indians without Masters degree who came directly to the US on H1B visa working as contractors before. I highly advise not to consider joining Paypal Partner's Integration team if you are looking for learning opportunities and growing your skills. Join this team only if you get rejected in all major tech companies and other cool startups in the bay area ( Basically, consider this team in Paypal as your last option).
