The webinar provided some good basic information. Two problems I had with it are that is seemed to be a commercial for their services and Rod was constantly using things like "Uhm".
I may not be selling my services as an interview consultant but over 20 years as a consultant in the real where the gigs could run from a few months to over a year, I think I have significant experience in being interviewed.
Constantly using "Uhm" or similar expressions can ruin an otherwise good interview. It can make one appear unorganized or as stalling to come up with an appropriate response. I hope that in their coaching they emphasize that quick and decisive reponses will go a long way in helping to "Ace" the interview.
Just my 2 cents.
