The case was with a company that had interviewed several people and shortlisted two people that could be appropriate. The two people had gone through the regular interviews with non-testers. I offered to spend 30 minutes with each candidate they thought they would be interested in to pair test and give an assessment of how they approach testing.
My assessment report for the company included an hour of video of screen & us testing together, and a summary of their strong and weak spots as I saw them. We tested the company's application for a pre-selected feature, in a test environment.
I opened the session telling we'd work as a pair with the rule of "I have an idea, you take the keyboard". I had the idea first to introduce them into the application and most of the session I would be the hands, as their ideas mattered.
In 30 minutes, I got to see the testers flow on how they get started with something new. I got to see
- if they would take notes / model things while testing.
- if they see bugs.
- how they model technologies and focus of testing.
- if they were dependent on external answers or could provide theories of their own.
- if they at the end of the session has ideas for making the testing deeper or if they were ready to move on to other features.
