4 Round of Interview wherein 1st round was technical and 2nd round was with HR and 3rd round again with Technical team and the Final round with manager. All round happened int he office

I had three rounds of phone interviews, one with the HR Manager, one was a technical interview, and the last one was with the Hiring Manager, who ended being my boss! The HR Manager phone interview was a walkthrough the resume while the one with the Hiring Manager consisted of a few behavioral questions, along with questions about how long I would stay with the company. The technical phone interview had questions on storage products, difference between SAN and NAS, how do you connect two computers. I then had a face to face interview at Bangalore with the senior manager, who again asked a few behavioral questions, after which I was offered the position in a week.
