A headhunter contacted me about a position for Cisco and asked me if I have any interest in it. Since it's a position working for cloud solutions that I wanna try, so I submitted my CV to him. After several days, I was invited by the hiring manager for a whole day interview. The interview was not that hard, just normal questions about linux, networking and developing skills. After that, I was invited to Cisco again for interviews with 4 different people. Still questions similar to last interview.
