Ascend Consulting interview questions

I received an interview call after a current employee referred me for the position of Business Analyst. There were roughly 5 to 6 rounds of phone interview, some of the interviews took place without any notice in advance. Their approach was very unprofessional. Last round consisted of a 1:1 interview with a practice manager, he was completely focussed on what Ascend was doing and preferred to ignore on what I wanted to achieve. Finally, I discussed with the HR and he was not sure if he was ready to sponsor temp visas and there was clarity on that. The Client Relationship Manager asked for my CV to be presented with the client and she never got back to me. Overall an unprofessional organisation to say the least. It was a complete waste of time.
