FAANG Interview Questions

Hello everyone, I hope you’re all doing well. Over the past few years, I have had the opportunity to interview with some of the most prestigious companies, including FAANG, Visa, and Walmart. I wanted to share with you some of the interview questions I encountered during these interviews. Let’s dive into it.

1. Introduction: Be prepared to provide a concise and informative introduction about yourself and your work experience.
2. Daily Responsibilities: Familiarize yourself with your day-to-day responsibilities in your current role.
3. Achievements in Current Projects: Be prepared to discuss the key accomplishments and impactful projects you have worked on in your current position.
4. Coding Problems: The coding portion of the interview usually begins with basic questions related to Python or any other programming language. These questions may cover topics such as strings, linked lists, trees, and more. Here are a few examples of coding questions I encountered in the past:

• Palindromic Substrings
• Sum of Square Numbers
• Binary Search
• Two Sum
• Longest Substring Without Repeating Characters
• 3Sum Closest
• Valid Parentheses

Please note that these specific questions may not be asked in your interview, as the questions can vary from interviewer to interviewer. It is important to be well-prepared in advance.

5. SQL Problems: Data engineering requires a good understanding of SQL. You should be familiar with basic normalization rules, problem-solving abilities, table creation, data cleansing, and the use of partitioning and bucketing. Here are a few examples of SQL problems:

• Nth Highest Salary
• Department Highest Salary
• Department Top Three Salaries
• Delete Duplicate Emails

6. System Design: During this stage, you will be asked to design a data model for a new system that ingests real-time streaming data. Be prepared to address questions from the interviewer regarding the nature of the data, its frequency, and the purpose of the system after data ingestion, among other considerations.

Remember, it’s important to maintain a continuous conversation with the interviewer. Interviews are a two-way communication process, so don’t hesitate to ask questions and seek clarification. This shows your interest and engagement in the problem-solving process, which the interviewer will appreciate.

Start preparing, techies! Consistently solving daily coding questions on platforms like HackerRank and LeetCode will greatly enhance your chances of achieving your dream goals.
