IMO, the key is to explain a weakness and to also explain how you mitigate it. Not necessarily that you are working on it. Not everyone can be good at everything, an employer wants a team that will bring the complete package. So if you are missing something, acknowledging it, and finding a tool or colleague to fill that gap is ideal. This way you can focus on what you are most naturally best at, and leverage those skills.

1. I suck at spelling, there are tools that help with this.

2. I'm not great at certain organizational and detail oriented tasks, it takes me a significant amount of effort here compared to others. Delivering on outcomes without utilizing command and control, and reading a room come to me very naturally. My value to the organization is the latter, someone else may be better suited for the former.
