Hi everyone,

I’m currently a final-year undergraduate student from a Computer Science background. I’ve developed a strong interest in data analysis—especially analyzing business data, building dashboards, and generating data-driven insights.

I have hands-on experience with SQL and Python for data cleaning and preprocessing, along with some statistical knowledge from both academics and online courses. I’m also very comfortable with Excel and Power Query. Additionally, I have some familiarity with cloud-based data systems and querying them using SQL/Python.

However, I haven’t yet worked with very large-scale datasets.

I’m aiming to pursue a serious remote role as a Tableau-based data analyst, and I’m currently in the process of mastering Tableau.

I was considering building real-world case studies using publicly available datasets—where I would analyze data, generate insights, and present them through Tableau dashboards, while documenting everything properly. I’d really appreciate some guidance from experienced people in this field:

1. How can I rise above the entry-level saturation and position myself as an intermediate-level Tableau analyst who can attract both clients and full-time remote opportunities?

2. Should I focus on doing many projects (like following end-to-end YouTube tutorials), or should I prioritize fewer but more in-depth, serious case studies?

3. Could you suggest a practical roadmap to reach this level within ~7 months?

4. What certifications would actually help my CV stand out for Tableau/data analyst roles?

Thanks a lot for taking the time to read this! 🙏

I came across a situation where I need to sort a calculated field based on other field so I went to sort tab and there was no sort by field option . I was working with live connection to database this problem occuring only in live connection but not in extract .The backend database query engine I am using is hive/impala .did anyone face similar issue .Any one know how to debug this issue

Lately I’ve been experimenting with a small LLM setup to help me debug Tableau dashboards and handle change requests.

What I’m doing is:

Taking the XML from the dashboard

Preprocessing it

Feeding it to an LLM

Then when a bug ticket or change request comes in, I just describe it—and it actually does a pretty good job pointing me to where the issue is and what needs to change. That part is working better than I expected.

But I built this as a POC with just 2–3 dashboards.

Right now I’m just storing the processed data as JSON ,and I know this is not going to scale at all.

If I want to take this further (say dozens of dashboards), what’s the right way to store and retrieve this data?

Should I be looking at vector DBs, Postgres, or some mix of both?

Would love to hear how others are approaching this, especially for LLM + debugging / analysis use cases.

In the next few weeks I’ll be conducting interviews to hire a Senior BI role that requires advanced Tableau knowledge. I’ve been burned in the past from people who claim to be very knowledgeable but clearly overstated experience. Aside from asking for a “portfolio” or a link to any Tableau Public workbooks, has anyone ever created or done a test project? For example, providing a same data set with questions that need to be answered and visualized?

I am looking to see if it’s even possible to make extra income outside of the normal 9-5!

Advice is well received!

What advantages does Power BI have over Tableau and Superset in the banking sector? Please help me analyze this, as I am proposing an automated reporting solution for the entire bank using Power BI.

Hey everyone, I for the life of my can't figure out how to accomplish this. I've reviewed scaffolding, pivots, etc but nothing seems to work. Here is the data structure:

Table 1: Customer ID and Customer Create Date (All records in this table)

Table 2: Customer ID and Customer Order Date (Some of the records in table 1 are in this table)

Table 3: Customer ID and Received Date (Some of the records in table 2 are in this table)

I am hoping to show a simple text table that has the number of customers created, number of orders placed, and number of orders received in the same view.

What is the best way to accomplish this?

Question: this is my first time going to the Tableau Conference.

I am interested in a few hands on sessions, does the laptop need to have Tableau Desktop installed, or do they work through the cloud for these?

Hi All,

I have a tableau dashboard published on the website which can have multiple filtering options such as location, product, area etc.

So I wanted to know if there is a way to download the dashboard using VBA/Python or any automated solution?

I am looking to download the same view as crosstabs > csv when i put in some inputs in the macro which can filter data and then download dashboard

Hi everyone, I’m trying to understand a simple but frustrating behavior on Tableau Server.

My dashboard was consistently stuck to the left after publishing, even though it was a fixed size (1280x1350) and 'Sheets as Tabs' was enabled. I didn't have any floating objects.

The Mystery: I randomly tried increasing the height to 1500px, published it, and it suddenly centered. Then, I changed it back to the original 1350px, re-published, and it stayed centered.

I’m glad it's fixed, but I have no idea why this worked.

1. Why does this left-alignment issue happen in the first place?
2. Why did toggling the height (and reverting it) fix the horizontal alignment?

Is this a known bug or some kind of rendering cache issue? Would love to hear the 'why' behind this!

I have to create set of combinations available in the dataset group. For example we have group 1 to group 10 with there own set of functions.

I need to find which combination of group has how many people. each person can have more than 1 group. So I need to display each group has how many people. . basically List_agg or string_agg but in tableau
