Do I need to have basic knowledge in every tool out there for data science?
If you can create a list of every tool existing in data science, that list itself will be fascinating to share with others.
After you have done the research to create such a list, add a few lines to summarise what each tool does and one or two pros and cons that you come across in your research.
Then as you reflect on these tools and your research about them, you will be better prepared to answer your own questions.
Your research and findings will be of immense help to other practitioners in the industry.
The discussion shared above was part of many Q&A sessions Harsh Singhal conducted with Data teams at various companies and colleges.
