Cisco Sr Software Engineer interview questions

Campus recruitment at college. Presentation about the company details and what they are working on. Written test on C and Aptitude. Coding round with group/panel. Coding round/ Individual. HR Round on attitude and basic logical and reasoning.

I applied for the interview 2 months back and one day out of blue, I got an email that we have scheduled an interview with one of the technical lead with 2 options. Please provide your availibility. I responded by saying No to both the times and asked to reschedule as I have my Production planned on same day. Changed the timing last minute and gave a timing of 2 pm EST. Interviewer calls me 2 hrs before and tell me I might have confused with the timing (even though I have email). Anyway, interview went well and he told me that wait for the next steps. I am still waiting ..... 1 months. I know I am not a snowflake or Ex-googler but if I spend 1 hr on the interview, company HR should respond with atleast a response (if not a detailed feedback). Pathetic process. Wouldn't apply or entertain call from Cisco anymore.
