There were 4 rounds of technical interview and after that went fine, I had 1 interview by director/hiring manager. Thereafter, the HR conducted a telephonic interview to find what I thought of cisco. There was a temporary hiring freeze for 2-3 months during which the CEO changed and after that was lifted, I had 1 interview with tech lead who explained the nature of immediate work and asked me if I could do that job or if I had done similar work.
