Workload days
Everyday Workload Vitali Dedkov, Lead BI Analyst/Data Engineer from Russia wrote in quora answer
“It varies, but for me a lot of time is spent working with our fellow Data Scientists group and our business group and trying to understand exactly what needs to be done and how to do it in a way that we can deliver results. quickly and cost-effectively.
This means that I spend my day working on data processing, testing result sets, and then reviewing them with end users.
On top of that, it also updates the documentation to ensure that if I want to see what I did months ago, I’ll be able to find something I wrote.
Once that’s all done, keep an eye on the latest news coming out of Azure/GCP/AWS on Data Engineering topics. This includes trying to find out news about more traditional ETL tools like Informatica, SAP BODS, and Talend.”
