Hopefully, I have successfully reverse engineered the process advised in this video so that my clients display appropriate interview behaviors to match any interviewer. Our goal is always to do what it takes to turn the interview into an offer. You can always turn down an offer if you think your are not a fit or it isn't quite the right opportunity.
But you don't want to hand over that power to the interviewer. You control your total delivery during the interview, not just what you say but how you look, sound and move when you respond.
The most scary statement a recruiter can make is to tell you to relax and be yourself. Do not do that! But this does put you on the alert to be very attentive to the recruiter's body language, mannerisms and the non-verbal feedback to the answers that you supply to their questions. That's exactly what they are doing to you!
Interviewing as an art should be a well choreographed dance between you and the interviewers. How many times have you lost out on a great position because you didn't read the interviewer correctly or rubbed them the wrong way? Record your voice as you practice answering questions. Use your laptop to video your practice interviews. Microsoft OneNote will actually record the screen as you to this so you can track your improvement.
If you get really good at interviewing in any situation, with any style of interviewer, and any company then you can afford to be your self when you want to not when they want you to.
