You buy the book and get a code to access a website. On the website you can enter your code to do a 177 question 'quiz'. You are only able to do this the once and then it's fixed. This even though the book itself says 'if you take the same version of StrengthsFinder again a few months later, it is not unusual for a couple of your top five themes to change.' So, you cannot then look at how strong each of your 'themes' is and cannot see how you might change over time after trying to apply some of the suggestions offered.
The book itself does give a description of the 34 themes, but the website doesn't really offer much extra. You can look at your results (but never retake the test) and look at the 10 ideas of action (which are in the book anyway). I was hoping for a lot more to be available on the website. More ideas, more questions to ask yourself, more ways to actually *use* the ideas and suggestions given.
Strikes me that this is little more a promotional tool to then pay huge amounts of money for further consultation.
Overall, not a complete waste of time, but I'm not sure it's entirely worth the money.
