UPDATE: Received f2f interview invitation the next Monday, flew into IAH yesterday, and completed f2f interview today. We had a small group of 8 people, we all got there at around 7:30. First we attended a presentation stating something a flight attendant should know. Then we were asked one by one into another room. I had two recruiter interviewing me, they were all very nice. I thought I did great in the interview, but after a short wait, I was told there was no further question for me and they let me go home. Some other applicant got 2-3 questions or same with me. Waiting for the email now. Good luck to me. :) Applied on 7/11, received video interview invitation on 7/18, took interview on 7/21. The video interview system is pretty easy to use. You can do practice before interview as many times as you want, I highly suggest you do that until you are used to speak to camera and look natural in video. For questions, you should prepare for the questions listed on glassdoor, that will be a huge help. Although there may be new questions, you can mix the answers you prepared and give the proper one to the question. Hope I can hear from United soon and be chosen to f2f interview. Hope this helps, wish me good luck please. Finger crossed! :)
