Focus on the basics like Excel, SQL, Python, data visualization, and statistical concepts. Apply skills to projects and keep sharpening through practice. Be patient with the learning process.

  1. Do I need to learn cloud tech (Amazon sagemaker, Azure etc.)?

    Big cloud service providers such as AWS, Azure, Google Cloud have their own ML offering such as Amazon Sagemaker in case of AWS. As a fresher it is ok if you are not familiar with these cloud platforms but once you have some experience it is good to have experience and know-how of at least one cloud ML platform.

  1. Do I need to learn Gen AI?

    Gen AI is a fancy topic and the majority of the junior data science positions do not demand gen ai skills. In case you have additional time and If you want to learn a famous framework for building Gen AI apps called langchain then here is the playlist:

  1. How about BI tool (Power BI or Tableau) 

    BI tools nowadays are mainly used by BI developers, data analysts etc. Hence It is ok if you don’t learn them as a data scientist. Majority of the time whenever data scientists have a need of BI dashboards they will take help of BIor data analyst teams. In small organizations however, sometimes data scientist work on building BI dashboards but in general you should not worry about learning BI tool for a data scientist career
