Cisco Developer interview questions

There were 3 rounds of interview, namely technical, managerial and hr. In first round my focus was on resume projects and few simple DSA question. In second round it was asked to show impact of project on industry. third round it was basic hr round with standard hr questions.

I was told that there would be one behavioral interview and one technical interview. However, my interviewer asked me a ton of theoretical networking questions during the behavioral interview, which I was not expecting at all. Did not receive offer even though I was told that I did well on the coding portion.
