HCLTech Senior Software Engineer interview questions

Well initially there will be 3 rounds.First will be 1 on 1 Skype/google meet call where they will discuss about your candidature and will shortlist you. Usually my recruitment agency told there will only 2 rounds 1 will be with HCL and another will be the Client (IBM) but this didnt happened for me that is the reason I giving worst experience. As both my rounds got cleared I received email that I have been shortlisted and there can be HR round anytime. So I was waiting for their reply to release offer letter but very next day they told me there will a HACKER RANK test though she told me my shortlisting is confirm I was like WHAT? firstly you are telling me I have been shortlisted and next time you are telling I have to write the test.Writing test was not a problem but there was some issue to clarify I called a guy from HCL I cannot point out his name but he was an IDIOT he didnt had any ethics nor professionalism to interact with a candidate who is applying in his company. He told me "I dont have spare time for you and I cannot give you a single minute" So this was reply I screwed that idiot like anything.
