The interview process was very simple and did not take longer than 10 minutes, but the process before the interview was long. We arrived at 0630 and found out that was just a waiting line that would start to enter after the earlier groups were already in. We finally entered the embassy around 0800 and had to sit and wait. Eventually, we got my wife's biometrics completed and the interview took place around 1100. We were out of the embassy around noon time.
