Below is the process I recommend that you follow, when you want to identify your customers personality type.
Research before the meeting
When researching your customers prior to meeting with them, do the following:
Getting Started
Start, by examining their social media sites and look at their pictures first, as they will give you great insight into their personality type (see explanation contained in each question, around what to look for to identify each personality type)
Secondly, examine the content they post on their social media sites. (See explanation contained in the question that follows, on how to do this effectively)
When you do this ensure that you once again use the process of elimination, to identify clues, which will help you to identify, each customers personality type.
Next, try to find pictures of the car they drive as this may also give you clues as to their personality type (See explanation in the question below, on how to do this effectively)
Please explore the questions that follow and after viewing all the clues, try to identify each customers personality type
