This guide is based on general FAANG interview practices and may not reflect specific company procedures.
The interview process for a Junior Data Engineer at FAANG companies typically consists of 6-7 rounds spanning 4-6 weeks of preparation. The process begins with a technical phone screen focusing on SQL and programming fundamentals, followed by 3-4 on-site technical rounds covering coding, data pipeline design, advanced SQL, and basic data systems architecture. A behavioral round assesses collaboration and cultural fit. Throughout all rounds, interviewers evaluate your ability to write clean, efficient code, design scalable data solutions, optimize queries, and communicate your problem-solving approach clearly.
