PayPal interview questions

I interview with team manager and then she gave me a dataset assignment. I finished the assignment and then they told me they are going to review all candidate results and get back to me in a week. However, they reject me in one hour. I was shocked and I think they did not even review my results. I feel truly disrespectful. I will never apply for any job in this company again.

Worst Interview experience ever!! The interviewer rescheduled my interview thrice (including once on the weekend) and failed to call every single time. He would call an hour late just to reschedule again. Never has anyone been so unprofessional in my entire life. Makes me seriously wonder about the work ethics of the people who are hired by Paypal.
