I am a student who has completed his master's and I took an year break to prepare for PhD and living in a poor Asian country. I applied to PhD programs in Germany and France this year in Pure mathematics and I have received 3 interview calls in January last week and February. 1 interview is with prospective supervisor alone and two are with admission committee of 4-5 members.
What cultural and etiquette should be kept in mind during Zoom interview?
Also, suppose In case I am not able to answer question of a professor (suppose being not able to recall or not so good in that field) then how should I handle that situation politely and without getting embarrassed ?
(I have only given one interview in my life (in person, not remote, for master's entrance) and I must say that I panicked because I was not able to solve the questions completely and hence said to prof. I don't know and in fact I felt a bit relaxed when that interview was over (despite being in good command over the topics that I was asked questions about and the program being one of my favorites). I have a problem of panicking in front of authority and have self esteem issues.)
I am putting emphasis on culture and etiquette because my country is one of the most racist country where people are not known for their politeness and are very sarcastic to each other.
So, what etiquette should I keep in mind while giving interview to be polite and well mannered person as per Western European standards?
Any advice, reference you give to me will be immensely useful to me and I shall be really thankful for that.
