Your second vdo is okay, but there are many parts in the second vdo which show that you and your friends don't really understand what Jay and Phillip said to you. In terms of the interview atmosphere, the second vdo is more lively and relaxing, but in terms of communication and interview manner/etiquette, the first vdo is better, I think. In summary, you can choose to submit the first or second vdo. Both of them are okay, but you have to choose only one. Also, don't forget that you have to prepare and present a summary of your interview in the class on Thursday 29 September.
