RUC Cementation Mining interview questions

Interview was okay. The interviewer didnot feel very keen on asking too many questions. After day after the interview, i got a call from HR that my interview stage was cleared and can move on to the next stage of medicals and reference checks. All of this was completed, however, I didnot hear back from the HR for a couple of weeks. Then after 2 weeks, HR called me saying the job listing is no longer available. I was almost going to resign with my current company, but I thought I would wait until I get the offer letter.
