As a data guy, my daily job was to manage large datasets - by cleaning and validating. Since I'm with a B2B companies before, I usually handle a set of contact lists. The tools that I've been using in this role were: Microsoft Excel / Google Spreadsheets, Zoominfo, -----------, LinkedIn Sales Navigator, HubSpot and Power BI for visualization.
As a customer support guy, my daily job was to assist customers via email and live chat using Zendesk. On a typical day, I handled around 60 emails and took turns managing live chat inquiries through a round-robin setup within the customer support team. PS: This is a FinTech industry.
