Not entirely certain this is the right place to ask this however looking through StackExchange I couldn't find an alternative.
In a couple of days I will be running through 10 developer interviews for a remote site. Our normal process is a technical test with a follow up interview. However as this is a remote site, and there is not likely to be frequent management presence there, I need the successful candidates to be more "engaged" than a normal head office developer. These kinds of aptitudes can come out of a normal interview, however I am also considering running some sort of group exercise to see how they work together.
Is this generally considered to be appropriate/a good idea?
If such a course of action would be beneficial, what kind of activity might be the most effective for this? My current line of thought is to give them a fake 3rd party API technical specification and ask them, as a group, to comment, review and create a series of questions that they would take back to the author. However this is more a single person, rather than group, exercise so I am not entirely convinced of its value.
