HCLTech S S E(Senior Software Engineer) interview questions

I got call from a consultancy ( Careernet) and I had cleared all the interview rounds including client round. HR was also ok with my salary expectation , she told me that she got salary approval also .But she didn't release my offer . Whenever I called her , she never picked up my call. So , I can say that process is pathetic.

Overall experience was good and questions was asked about java and spring serve lets. they are very moderate questions. then theoretical questions were there. Then HR took the next round of interview and asked multiple questions
