After you have introduced yourselves,
We will ask some simple questions – one each
Then we will ask each of you a question like“Tell us about the most interesting engineering project you have done so far”
You should have an answer prepared – 1-2 minutes each
This (or a similar question) is very common in interviews
Practice it now
Then each of you will get 1 or 2 more general questions,perhaps based on something in your CV
