5-6 stages Interviews

I submitted my CV through one of my friends who worked there. They contacted me through phone and made a small phone interview then gave me the date of my first interview. The first interview was with my team manager but before the interview I had to do a computerized IQ test and another Technical test (CCNA basics) which I passed and I didn't take CCNA but read about it a couple of days before the interview. Through the first interview my manager explained the position's objectives then he started asking about my personal skills and 3 easy technical questions. After a week, I was contacted for a second interview with my manager's manager and it was very easy. Then had my HR interview a week later and it was a professional one.Finally had my final interview with one of the GM assistants which was easy too.
