Seeking Insights into Data Analytics Projects

I've been working in the SharePoint domain and recently completed two years at Cognizant. Unfortunately, I didn't get any work during this time. However, I discovered a passion for data analytics and now want to pursue a career in this field. I know the necessary tools, but most companies require experienced candidates.

I've given two interviews but felt unsure while explaining projects.

I would appreciate it if someone in the data analytics field could provide an overview of their real project. Specifically, I'd like to know what they did, their role, the length of the project, and how everything worked in the company.
