Cisco Software Developer interview questions

Submitted a cv, then I was given an iq style test for 30 min and then had an in person interview that was fairly relaxed followed by another one afterwards

Had virtual onsite interview with Cisco. There were 4 rounds in total, and the experience was very bad. The last interviewer told me to wait as there would be an extra round. I waited online for 90 mins, and no one joined the meeting. I sent email to the manager and did not get any reply. There is no respect from this company, very disappointed.
