Wipro Business Analyst interview questions

I had 3 interviews with 2 persons (1 HR and 1 Bussines). Both of them located in India but the opening was for Germany. The interviews were very disappointing. The interviewers actually didn't have any knowledge of the business and the requirements of the position. Most of the questions were from my side and I received general answers. After 2 weeks I have sent an email to the Hr executive asking for feedback and they told me that the position is most probably frozen. After almost a month HR email me asking if I am still available. I gave them a positive answer and after this nobody came back to me:) This is by far the worst behavior I have ever met during interviews.

It was a 3 step process. First was a MCQ, 2nd technical round and 3rd HR round and it took a month for the entire process and I got a offer letter just before the joining date
