Skills required for the Facebook Data Science Interview


Technical interviews tend to have the same general pattern, right from asking to introduce yourself to talking about your experience, followed by technical questions to know the competencies of an individual. Depending on which type of data scientist role you are applying for, questions will be asked, so if you are all set for an interview with the Facebook team, here is the list of required skills that will help you.


Programming Skills 


If you are wondering from where to start preparing for the role of data scientist, coding is all you need to learn and practise. Having expertise in any one of the programming languages can help you in a long way. I would recommend having hands-on experience in R or Python as these coding languages are in high demand. With these, you can manipulate the data and apply specific algorithms to draw meaningful insights.

In-depth knowledge of SQL 


For a data scientist role, it is crucial to have a profound understanding of relational databases for writing queries and sub-queries. One should have a prior understanding of using the right clauses at the right places, along with the knowledge of SQL operators. One should be able to store and retrieve information from the relational database as this will make it easier for you to pass the interview.

Key Concepts of Probability Theory


To pass the technical portion of the interview, it is crucial to have an understanding of the basic concepts of probability and statistics like a central limit theorem, independence of events, and more. You may be asked to build practical intuitions for the theories of probability or to evaluate the outputs of probabilistic models. The concepts of statistics will help you make better business decisions from data.


Knowledge of Big Data


As Facebook stores an enormous amount of user data, it is crucial to learn the concept of big data if you are planning to sit for a Facebook Interview. Currently, the platform of Facebook is using big data to manage trillions of user data. As a Data Scientist, it is vital to have a grasp about frameworks that can process Big Data, ‘Hadoop’, and ‘Spark’ being the two major ones.


Machine Learning Algorithms


Excellent hands-on knowledge of various machine learning algorithms like supervised and unsupervised algorithms is a significant add-on skill. To solve complex problems based on predictions and to handle large sets of data on Facebook, it is crucial to understand machine learning algorithms.

Such skills will help you in data analysis, processing, visualizing, and modelling in data science projects.


Apart from these technical skills, a mixup of communication skills and practical experience will help you pass the examination of Facebook.


From Where to Learn?


If you want to land a job offer from Facebook, you need to prove yourself exceptional. Along with developing those five skills (mentioned above), getting certified from the top platforms will be a major advantage. There is an extraordinary impact of certifications on the lives and careers of thousands of respondents across the globe as certified professionals have more chance of getting jobs.
