I used to have a “don’t know/can’t remember” man in my team.
Can you recall what this code you wrote previously do? “I can’t remember.”
Do you know where the files are placed? “I don’t know.”
Where are the documentations for xxx. “I don’t know.”
Do you know the difference between xxx in testing in production server? “I can’t remember.”
It was frustrating.
9 out of 10 questions were “I don’t knows” and “I can’t remembers”.
I’d much rather he said yes or no.
