I applied online. I interviewed at Cisco (Bengaluru) in Jun 2026
Interview
The interview started well and covered backend concepts, Java, system design, and coding. I answered the questions confidently and had a positive interaction throughout.
After receiving the rejection, I spoke with HR to understand the feedback. I was informed that the interviewer believed I was looking at answers during the interview. This came as a surprise because I was not referring to any external material. I have a habit of looking away while thinking or recalling concepts, which I believe may have been misunderstood.
I wish this concern had been raised during the interview so I could have clarified it immediately. If there are concerns about a candidate’s behavior, discussing them in real time or asking for a room scan can help avoid misunderstandings.
Overall, the interview questions were fair, but I feel my evaluation was influenced by this misunderstanding rather than my technical performance.
