PayPal Software Developer interview questions

Round 1 had 2 coding questions in Hackerank platform . Both of them were hard. We were given 2 hours. In round 2 they asked me to explain my internship projects and academic projects. Two coding questions and few ML,DBMS questions.

Contacted by a recruiter. I took an assessment that I was given 24 hours to complete, then told I would have 1 interview. I ended up having 3 interviews, each taking around 45 minutes. The interviews were okay, all were technical and get to know me. 2 of the interviewers didn't seem to care and were grumpy. Asked a lot of whiteboard questions.
