SuperProcure Senior Software Engineer interview questions

I had three rounds of interview of one hour each and after all the rounds the HR asked me to submit the document as they are going ahead with my candidature and after submitting the documents, after constant follow up, I don't get any status of my candidature. And after a long they send me a message that they are not going ahead with my candidature. Negative experience, never recommend this company to anyone as they just waste your precious time.
