The Google Interview Process Google’s interview process comprises three main rounds of interviews: The Technical Phone Screen Interview: This is essentially a screening round to filter candidates based on their proficiency in a programming language, and their ability to solve simple coding problems by employing programming fundamentals. The On-site Interview (comprising 3-5 rounds of coding and other technical skill assessments): In its on-site technical rounds, Google tests extensively for problem-solving skills. Questions center around your proficiency in core technical areas such as data structures, coding, algorithms and systems design. Typically, for Google coding round questions, you’ll need to answer these questions by coding on a real-time, collaborative editor or writing code on a whiteboard, depending on whether it's on-site or online. The Behavioral Interview: Behavioral questions are an extremely important component of Google interviews. Candidates are often put through many rounds of behavioral interviews. This is to help recruiters understand the attributes you will display in workplace-related situations. While every candidate mandatorily goes through a behavioral interview round, these interviews are considered more important while recruiting for upper-management positions, e.g., for the role of Engineering Manager or higher.
