eBay Senior Business Systems Analyst interview questions

Recruiter reached out to me very next day of my application (through employee referral) I had a phone screening and then 4 phone interviews with different people. But, the process itself was lousy. They rescheduled my interview meetings several times. 1 interviewer just did not show up on phone and later rescheduled. Another director was 20 mins late to the interview. (yes, I was holding the line for 20 mins) After all these interviews, they told me that they were interested but, are no longer planning to fill up the position at this time and provided me no other feedback. Just wasted my time!
