Trending @Infosys; Clarification Regarding Skill Tag Change

Hi infosians

I noticed that earlier (around 2024) my profile had a “Premium” skill tag, but recently it seems to have changed to Niche. I’m not sure when or how this change happened. Could you please help me understand how skill tags are updated or changed?

Also, do we need to take any specific actions or meet certain criteria to maintain or regain a particular skill tag (like “Premium”)?
