3 rd round (30min) Hiring Manager Round - genral discussion about project. detailed discssion on each project bullet point. why how and what. (like authentication vs authorization, jwt, mongodb vs firebase vs mysql).
at last he told me to ask some question and that's it.

last update - recieved a rejection on mail after engineer manager round. on asking for feedback from hr. he told me that em said i was not confident while explaning the project. need to focus on more basics of projects. on asking about DSA round hr told it was the best feedback as compare to all the candidate.
