Epicor Software interview questions

Worst experience of the interview in my entire career. First I was told that there will be 1) Online Coding Test 2) technical Discussion 3) Technical Discussion 4) HR. After clearing the online coding round and two technical discussions to my surprise they conducted one more Technical Discussion that also I cleared after that again HR told there will be a manager round that also I had cleared. After that everything was cleared and I have got the official congratulation mail stating that I have cleared all round of interviews and they require my documents. Then suddenly HR told me that there will one more personality online test and aptitude test whoosh that also I had completed. Then HR told me that Director wants to speak with me I said ok. Next day when I checked with HR regarding the joining and all to my surprise that she told that Director was not convinced with me and they have to stop there when I demanded a justification for that she told that my salary expectation is also high. So HR and Mr Director this all had been discussed before the initiation of the interview process. Please have some ethics and first check your budget before conducting the interview. You don't have any right to waste the time of other person like this.
