Dear Helen, You have asked a question, but you have given an answer in your post itself. You have written, "I will have the 2nd stage of the presentation interview where they will show a few presentations and questions will be asked."
Preparation for Presentation Interviews
Has the future company informed you about the subjects the presentations will cover? If yes, it will make your job a little easier as you can read up on the topics. However, if the subjects are not confirmed, it could make your job a little more challenging. Nevertheless, this is a novel way to conduct interviews. My interpretations of this method are given below:
a) Take notes when the presentations are shown. This will help you ask questions, seek clarification, or provide replies. Ask the interviewers well in advance whether you are expected to check the spelling and grammar of the slide contents as well.
b) Please note that your interpretation will depend on your subject knowledge.
c) Try to read the lines and also read between the lines. The latter is tougher than the former; it requires presence of mind. If you can read between the lines, you could impress the interviewers.
d) Lastly, try to identify any logical inconsistencies in the slides or among them. Bring any inconsistencies to the interviewers' attention with their permission.
e) If you feel that insufficient information is provided, inform the interviewers that comments could not be made due to lack of information.
I hope the above points help in your preparation.
All the best!
