Manager interview first. Manager was young and amateur in my opinion. And interview experience was not good in general. HR was super friendly and explained everything. Even about company financial position etc.

Started with a HR interview. HR interview was pretty professional. 5 start for the HR interview. Followed by a manager interview which was not success in my case. Feedback from him was that I didn't explain in detail of the concepts he asked. I felt that i was not asked follow up questions. Manager interview last about 15 mins. Good experience for me as well in the end.
