How did I contact with my interviewers and how did I did follow up with them?

  Basically, I did the interviews through email as it was the easiest way to contact with people and it would be the most confident way for people to reply as they can do it anytime which make everything easier.  

  Moreover, I was nervous doing interviews through a video call because of the language barrier but I understand that I should tackle the problem as soon as possible.

  Once I got their reply, I kept chatting with them through the email, by looking at their answers, I did some research based on their answers such as their favourite designers which may inspire me. Hence, I did some research and looked at their works.
