PayPal Software Engineer Intern interview questions

The interviewer was not in the mood to take the interview thats what i felt from his voice the interview was scheduled between 1 to 2 in the luch time may be thats the reason he was no in the mood at all. he gave me 2 questions to solve and did not interact at all.

2 rounds of interview. A technical round and managerial round. The technical round involved a medium DSA question based on Linked Lists. The managerial round quizzed me on my understanding of projects, the design choices I made as well as my understanding of the Software Engineering process while building them.
