The time it takes to learn Tableau depends on your experience level and goals. Here's a quick breakdown:

• Basics: If you're new to data analysis, picking up the fundamental concepts of Tableau can take 2-3 months with regular practice.

• Proficiency: To become proficient in using Tableau for various data visualization tasks, expect to invest 4-6 months of consistent learning and practice.

Remember, these are estimates. Factors like your prior experience with data analysis software and the intensity of your learning can influence how quickly you pick up Tableau.

A Tableau Developer is like a data magician who uses Tableau to turn numbers and facts into easy-to-understand pictures (visualizations). They need a mix of skills:

• Tableau skills: Knowing Tableau inside and out, like connecting data, making charts, and building dashboards.
• Data tricks: Being able to clean and connect data from different sources, like a detective gathering clues.
• Understanding data: Knowing what the data means so they can turn it into the right pictures.
• Communication skills: Explaining those data pictures clearly, like telling a data story.

Some skills like SQL and scripting are bonus points! Overall, they bridge the gap between data and clear communication using the magic of Tableau.

Tableau is great for reports you want to showcase, like a slide deck for data. It lets you make clear and colorful charts to tell your data story.

But for super official reports, like financial statements, Tableau might not be the best fit. Imagine it as a presentation tool, not a printing press. Reporting tools are like fancy printers with lots of settings - they can format the reports exactly how you want and send them out automatically, but they might not be as good for making those charts shine.

So, use Tableau when you want your reports to be clear and engaging, and use other tools for super strict formatting or automated sending.
