HCLTech Senior Software Engineer interview questions

I was contacted by the Recruiter through email. I attended the weekend drive on May 2017. Interview is not that much difficult If you are good in basics and some programming logical skills it was good enough to crack the interview.The Technical Panel are good, I have cleared the 2 Technical rounds after waiting for more than 4 hrs . Finally HR round . HR asked about some details and salary expectations,I was informed that in a day or two we will contact about the further process. Even after repeated reminders for more than 2 weeks no response from HR/Recruiter. Do not waste the candidates precious time if you guys are not ready to release offer letter.
