"Semi-structured" interview

As I'm very satisfied with results of the unstructured interview (unfortunately recorded with a poor quality), I've tried to do a new exercise trying to do a "semi-structured" interview to a new voluntary. He belongs to the 3rd profile (people with knowledge in technologies -tech background- and use technologies to work as usual tools) as it was the case with interviewed during the unstructured interview.

The result is shown in the following video.
