What should I learn first big data or Data Science?
The basis to any attempt to answer the question of which to learn first between Data Science or Machine Learning should be Big Data. Why this is so is very simple. It is on Big Data that both Data Science and Machine Learning are built. These two technologies are unthinkable without Big Data.
Is HackerRank good for data science?
No. HackerRank tests are sometimes not good ideas to hire data scientists. This is mainly because the Hackerrank platform encourages a particular style of programming expertise (competitive programming) which has no correlation to actual datascience skills.
What is the best site for preparing datascience interview?
Glassdoor
Is Big Data necessary for Data Science?
The vast majoroty of datascience work does not require big data tools. Both because most problems don't have so much data available and because computers are rather large these days.
Is HackerRank good for Python?
HackerRank is a good platform for starting Competitive Coding. Step 1 — Select a programming language and stick to it. Select one of the languages from C++, Java or Python whichever you are comfortable in.
What can I expect from a datascience interview?

Should I learn Data Analytics before Data Science?
In order to develop your dataand communicate your results, data analysis is essential to learn and practice as a data scientist. Not every day-to-day as a data scientist will be optimizing parameters with grid search methods, but it might entail coming up with a dataset from data analytical tools and functions.
Does data analytics fall under data science?
Data science is an umbrella term that encompasses data analytics, data mining, machine learning, and several other related disciplines. While a data scientist is expected to forecast the future based on past patterns, data analysts extract meaningful insights from various data sources.
