Riverbed Technology interview questions

The interview started with a recruiter reaching out and asking about the current and expected salary. Then an interview round was scheduled. Round1 - The interview time was supposed to be 1 hour. The interview seemed utterly inexperienced about interviewing. He did not understand how to phrase a question properly. The first question was a generic scenario about traffic dropping on a LAN network. I tried to answer by peeling layers of the TCP/IP model and soon understood that the interviewer was not tat familiar with all the layers in the stack. He kept mumbling something without giving any direction. In fact he initially claimed that the routing from point A to point B has no problems but later claimed that the IPsec was broken. I am not sure how can two endpoints route traffic if their security mechanism is broken. The second question was a coding question. A simple question that the interviewer unnessasarily complicated. I asked a few questions to clarify what he wanted but it looked like he no experience in asking coding problems. He said that I should not ask questions and simply code lo. Anyway, i did code a brute force solution and then wanted to move to a more efficient solution but he stopped me and said he was satisfied. I am sure he knew nothing about deeper coding concepts. The call lasted an hour, I was disappointed with who the interviewer was but I expected them to schedule another round. The HR never reached out even though she said she would . Summary- Very poor interview style and inexperienced interviewer. Feedbacks are not detailed at all. Needs a ton of improvement.
