bp Product Analyst interview questions

The Bp follows the worst interview process. My interview started on 6 October and I was asked to give a test. I passed the test then my interview was scheduled for 19th Oct, the interview went super awesome but they said my profile matched more to a product analyst, then I appeared in another hiring manager round on 7th Nov. I cleared the round, and after that my two technical rounds was scheduled for 15th nov but it was canceled without updating me, then my technical round 2 was also canceled. Then both the rounds were scheduled again for 15th and 23 Nov. T1 happened but T2 was again canceled. 3 HR were involved in the process but none of them knows what was happening. This process has wasted so much of my time.
