CitiusTech Technical Lead - I interview questions

I got call from HR about Telephonic Interview. After that i got call for F2F Round. F2F Technical Round was good. I given almost satisfactory answer to question asked by them. After that they said Sr. Project Manager will take another Round. after 10 minute, Sr Manager called me, He was asking Typical HR type question. Don't what he was expecting the answer from me, after 10-15 minute discussion, he said to wait for Recruitment Team. After 10 minute i got a call from Recruitment team in reception. She said me to leave today, HR will get back to you. After that no any call from HR.

First telephonic interview. Then F2F interview at Mumbai office. Interviewer did not give constructive comments on answers. Asked about OO concepts in very short, data structures a little bit, Dll types but not clear which types he was expecting, stack winding unwinding. Then another question was asked on linked list. But did not get any proper feedback.
