essprsodoseThe video questions were not very complex. You generally will get behavioral questions such as, what would you do if you are faced with a particular XYZ situation in office, how would you chose your group members as a leader etc.
You need not stress about it. My advise to you would be: after listening to the video question, take a deep breath, understand each word of the question, in your mind frame an answer that attends to all the aspects of the video essay question. It is important that you tackle each part of the essay question. For eg: If there is a question, which asks 'How would you chose your team members and why', then ensure that you have answered the 'How' as well as the 'why'. Plan your response so that you get time to answer both, the 'How' and 'why'.
If I recollect rightly, you get 30 seconds after you hear the question to form an answer and speak in front of the camera. While I agree that during such anxious moments 30 seconds are too less, 30 seconds are long enough to gather your thoughts and may be scribble couple of words in your notepad. Be rest assured that the text of the video question will still be flashing on the screen all throughout your video interview.
As regards your last question: No. Your video essay is a part of your MBA application and your application is deemed to be incomplete until you have completed every section of the application, which includes your video essay.
Trust I have cleared your queries.
