Frequently Asked Questions

Data Science Interview Process Outline

The typical Data Science interview process at FAANG+ and other Tier-1 companies looks like:

One coding round: Easy to medium Leetcode problems or Python-based Data Manipulation and Wrangling questions. SQL is often a part of these rounds.

Behavioral round: Open-ended questions to gauge if you’re a “good fit” for the company.

One problem-solving/discussion round
One take-home assignment round
1-2 domain rounds

Behavioral round: Open-ended questions to gauge if you’re a “good fit” for the company.

What to Expect at Data Scientist Interviews

One coding round

Easy to medium Leet code problems or Python-based Data Manipulation and Wrangling questions. SQL is often a part of these rounds.
The SQL round is pretty standard across all the FAANG+ companies. You’ll be asked to solve problems using common clauses such as JOINS, WHERE, and GROUP BY.
Google tends to focus more on Statistical coding, some Data Analysis, and SQL since the company handles vast data sets.

One problem-solving/discussion round

Inclined towards discussing your work experience, past projects, and problem-solving with a mix of statistics, coding, probability, and some quantitative aptitude questions.
Facebook (Meta) focuses more on real-world data problems. So, prepare accordingly and provide concise answers when asked to elaborate on statistical terms.

One take-home assignment round

Some companies give a dataset and inference-based questions to judge problem-approach/deduction skills as part of take-home assignments. The usual deadline is 24-48 hours.
For the take-home assignment given by Apple, you’ll only be provided with three days. It will probably be a Machine Learning problem, and you’ll have to develop a model and give a prediction using the dataset.

1-2 domain rounds

This round demands a deep dive into Data Science fundamentals. Interview questions in these rounds typically focus on designing experiments to meet certain business goals, A/B testing, and ML algorithms.
You’ll need to be clear about how you frame the problem, the metrics you use, A/B testing, technical trade-offs, and so on, along with the required data analysis.

One behavioral round

You can expect Data Science interview questions on your job experience and discussions on past projects along with open-ended questions to gauge if you’re a “good fit.”
When applying at Google, ensure that you have an answer for “Why Google?”. Such questions are asked at all FAANG+ companies.
Thoroughly research each company’s leadership principles and develop answers in the form of a story based on those characteristics.

Data Science Interview Questions

Data Science interview questions can be based on a variety of topics. You can answer them if you identify common fundamentals.

Try answering these Data Science interview questions:

Write a code that takes a number from the user and outputs all Fibonacci numbers less than the user input.

Given: The CDF of a distribution. Find: The mean.

Given: Two numbers a, b ;a<b. Find: Output of f(a,b) = g(a) + g(a+1) +g(a+2) +…+ g(b-2) + g(b-1) + g(b), where g(x) is defined as all Fibonacci numbers less than x.

Given: A number X. Find: The smallest sum of two factors (a, b) of X.

Given: Person A decides to go on a skydiving trip. Based on his research, the probability of a glitch resulting in death is 0.001. Find: The probability of death if A goes on 500 skydives.

Domain-specific Data Science Interview Questions

Define the ROC curve.

What is meant by the true positive rate and false-positive rate?

What are the steps involved in making a decision tree?

Given a data set consisting of variables with more than 30 percent missing values, how will you deal with them?
