As per my experience, it's very difficult to get a right employee who has very good judgment, sharp focus, attention & great observation skills.
Earlier it was very difficult to filter right candidate but our team come with some solution for that We made some minor changes in our interview process as follows:-
Now before conducting F2F interview We give some Android/iOS application's & instruction sheet to the candidate and ask to perform any type of testing(functional, GUI, Usability, Security....etc ) & find any kind of the bug based on this instruction. We give around 1 hour time to the candidate to find bugs as much as He/she can find. If the candidate is able to find even a single bug then we go for next round F2F interview otherwise we don't proceed with the candidate.
This small change saves a lot of time of our working employee & it helps us to figure out these basic qualities of the candidate like.
- Judgement Capability
- Decision making capability (Bug or not)
- Attention to details (Instruction sheet)
- Efficiency of the candidate
- Focus on random application (Layman approach)
- Flexibility with the situation & work
- Time management
- Observation of the random application....& much more
Then in the F2F interview, we start to ask the question-related to AUT we ask about his experience about that hour and Other skill sets (In resume) And try to judge the above properties in a good candidate.
I can't say that it is a standard procedure but its help us a lot to filter out a very good candidate from crowed, for our work.
