Mphasis SSE/ML/PL interview questions

It was scheduled walkin interview , there was quite a long wait and finally I was called for the interview . I had technical interview face 2 face with the technical guy. The guy asked me general and average questions . Latter after sometime I was told that I was through the technical round and had to go through the hr round . We had the salary negotiations and the designation also . I was told to send my details as soft copy after which they will send me the offer letter, which I did. 4-5 days after the interview no one came back to me . I latter inquired the hr what happened which she told me that I did not have the original documents so they could not proceed. After much dicussion she told me to meet her directly with the original copy of my current company offger letter , paysplip. 10 days after the interview I met the hr in person and showed all my original documents . She told me that she will send the offer letter within 3 days .On the third day when I called her , she is not giving any definitive reply when she will send the offer letter. Latter I got tired and forgot about the whole issue
