8 Data Skills Every Fresher Must Master in 2025
to Secure Remote Analytics Internships
Remote-first companies are hiring — but only those who can deliver insights from day one
Why Data Skills Are Non-Negotiable in 2025
With over 70% of analytics roles now remote-first, companies no longer wait for campus placements. They hire freshers who can clean, analyze, and visualize data using cloud tools — all from home. The good news? You don’t need a degree in data science. You need targeted, practical skills that solve real business problems.
