[SDE] Design discussion tips

I am an introvert and am unable to take part actively in design discussions and this hurts my visibility. Also, if I do ask any questions and it gets answered, I am unable to think of follow ups as I am more focused on just getting it over with. I think this can harm my career in the future. Any advice on how to think better on the spot and take part actively in design discussions? Blind tax: YoE: 2.8 TC: 28L
