Do not be trivial. It would take disloyalty to the organization, violence or lawbreaking to get you to object. Minor objections will label you as a whiner.
There is nothing like NOT able to work with. Organizations are made of teams; therefore one team member may be a notch slower than other members of the team. It is the responsibility of "other" team mates to help the slow team mate to match-up.
Can you describe for me a difficult obstacle you have had to overcome? How did you handle it? How do you feel this experience affected your personality or ability?
