IndiaMART Javascript Developer interview questions

I was interviewed at IndiaMart, Noida. There was 1 HR round, first technical round and selected candidates were interviewed in second technical round. After clearing these I was called for a final round with a senior employee (Director/VP) . I was confirmed after that round that I have cleared it and the HR asked for my documents & confirmed that she will send offer letter the next day . When I didn't receive the offer letter, I called her she said she will send it in next 2 days. I followed up with the HR for the offer letter and for the next few weeks she kept on giving the same excuse that they are asking for salary approval from the senior employee. After 2 months she clearly told me that I had less experience then they were looking for although I had told my experience in HR round and mentioned the same in my CV.
