Which are the top 3 problems that are on top of the Data Science, either based on industries or based on technology area?

Vaibhav Verdhan: We face data availability as the first challenge. It is followed by data quality and finally the availability of resources like server space, computation power, etc.

Advice to Aspiring Data Scientists

According to you, what are the top skills, both technical and soft-skills that are needed for Data Analysts and Data Scientists?

Vaibhav Verdhan: Coding (Python/R and SQL). Statistical concepts and ML basics. Soft skills will be communication skills, collaborative and storytelling

How much focus should aspiring data practitioners do in working with messy, noisy data? What are the other areas that they must build their expertise in?

Vaibhav Verdhan: Messy data is a truth and we have to face it every day. We spend 60%-70% on it. Aspiring data practitioners should know how to deal with missing values, outliers, NAs, imbalanced datasets, etc. 

What is your advice for newbies, Data Science students or practitioners who are looking at building a career in Data Analytics industry?

Vaibhav Verdhan:

1)Programming and software skills – R/Python, SQL, and Excel
