Don’t answer the question, ask them for specific examples on why they think you are being unmotovated or unfriendly, don’t be aggressive, just pretend you simply don’t understand. They’ll tell you some bullshit and you can tell it’s a misunderstanding. Keep a polite and friendly tone.
Not all positions require outstanding motivation. If you are a project manager, sure a motivated one will probably outperform someone there just for the money that doesn’t give a shit. A technician on an assembly line? It doesn’t matter, you are there to operate a machine and motivation will not make you (sustantially) more productive, incentives on the other hand will (benefits, salary, less stressful working condition…)
