SonicWall Software Developer interview questions

I applied through a Consultancy, Had a telephonic round first where they asked questions like DHCP Relay, difference between EMS/NMS testing, and some on selenium. Although I did not answer much I got into second round where they asked me to prepare for a 4-5Hrs Interview. When I first went there The Manager himself came to reception and took me to some meeting room. He was good and we had a long chat about my life and career history, and he took down each and every information on his dairy. Later he asked couple of technical questions, which I answers , but could not answer couple which I did not mention in my resume. After 2 hrs of discussion, he asked me to sit and called another person to take another technical rounds, It was easy as I was prepared for it. Mostly these questions are same as what he asked in the telephonic round. Once He is done with the interview, he went asking me to wait and after 5 mins , he came back and said I can leave at which point I released probably the HR is on leave.
