PayPal Analytic Support interview questions

The 2 first parts of hiring was good (analytic test, and interview with the team lead and another person from the data department). The last interviewer in the next step wasnt nice, she tried to made me say that in not really into this job,and talked to me in despise manner..it was really bad conversation. afterwards they forgot to tell me that they will move on with other candidates(3 weeks), and after I send few emails they said " you dont understand the business case of the company "- that they never asked me about. Really bad attitude to the candidate, will not recommend any of my friends.
