6 technologies in this stack — ordered Core → Edge → Hybrid bonus. Click any tile to start practicing.
Core — lands the role. Baseline skills hiring managers screen for. Master these and you can land the role at market CTC.
Edge — lifts your CTC band. Rarer skills that strengthen negotiation — they can push the offer toward the top of the band (e.g. ₹30–40L+ for senior data roles).
Hybrid bonus — broadens your profile. Cross-domain extras (e.g. Power BI for a Data Engineer) that open hybrid roles and raise your profile weightage with recruiters.
