What will you say when you are asked if appointed how soon after notification of selection could you take up duty in an interview?

If appointed, I would be able to take up duty within [insert specific time frame, e.g., two weeks] after notification of selection. This timeframe allows me to ensure a smooth transition from my current responsibilities and to adequately prepare for the new role. I am eager to begin contributing to the team and will prioritize making the transition as seamless as possible.
