Introduction –

Would not that be surprising if someone says he or she is not aware of Facebook? Undoubtedly, a majority of us most likely uses this social media platform for a while every day. As of December 2019, Facebook has got 2.5 billion active users monthly. This might just be an exciting fact for common users. But can it just be that for a Data Science enthusiast? Not at all. I am sure you are looking at all the data Facebook amasses every month from across the globe. The abundance of data means opportunities for Data Scientists. Not just that. Their recruitment from IIT-KGP with lofty annual salary had earlier created massive ripples for fresh graduate job seekers. So if you are wondering how to land up with a job at Facebook, look no further. We are going to talk about important tips to prepare for Facebook Data Scientist jobs.

How does an interview process at Facebook look like then? Let’s find it out.

Interview Process at Facebook –

The interview usually comprises of 2 stages. They are Phone Screening and an Onsite interview.

Phone Screening will aim at understanding the genuine interest of the candidate for the job. This will help the recruiter know more about the interviewee and his past relevant experiences. You might be asked some scenario-based questions.

Example Questions:

  • Tell me about a time you started analysis with certain expectations, and then got unexpected results.
  • Tell us about a project that you’ve managed and describe it from beginning to end.

Onsite Interview will breakdown into a couple of rounds: Coding (SQL, Python, or R), Statistics, Analysis Case — Applied Data, and Analysis Case — Product Interpretation. The rounds are usually short. Accordingly, one will require Data Analysis, Statistics, product intuition, SQL coding, and a lot of communication with business and key stakeholders as a skill set. Being a product based company, the interview will focus more on the business side in comparison to engineering.

Confused? Well, don’t be. You must definitely be wondering what kind of questions to expect in these rounds. We are sharing some example interview questions for a better understanding.
