Wipro Software Test Engineer interview questions

I got call letter from third party hiring team to attend interview, got selected to wipro. They took around one month to release my offer letter. After releasing my offer letter, I tried to contact them regarding to know about joining date but none of the HR team responded. I was very happy when I received my hard copy of offer letter from wipro and my resume status was in pending join in their portal and I resigned my current company on the same day. I got shoking news after 20 days of releasing offer letter saying requirement got freezed from client side so we are aborting your offer. Then my resume status came back to To screen and status as Offer aborted !!!!!!! Please do not trust this company and spoil your life. I have all the proofs(step by step), please share this : it may help others.
