Google L4 Interview Experience: Tips and Insights

If you’re a software developer or a recent graduate looking to land a job at Google, you might have heard of the infamous Google L4 interview. Landing a job at Google is already an impressive achievement, but reaching a L4 position means that you will work on some of the most challenging and impactful projects at Google with a higher salary and more responsibilities. In this article, we’ll dive into the Google L4 interview experience, its importance, and how to ace it.

Preparing for Google L4 Interview

Understanding the Role and Responsibilities of an L4 Engineer at Google

Google L4 is a senior software engineer role, awarded to those with 1-5 years of industry experience or high potential new grads and PhDs. L4 engineers are responsible for contributing to the development and implementation of large-scale systems, maintaining the quality of code, and mentoring junior engineers. They also collaborate with cross-functional teams to successfully deliver projects that meet business requirements.

Studying the Relevant Technical Skills

Google L4 interview focuses on testing an individual’s technical knowledge and skills. Technical skills required for the interview include data structures, algorithms, system design, coding abilities in Java, C++, or Python, and knowledge of distributed systems and databases. Candidates can expect to be presented with complex problem-solving questions and coding challenges during the interview. To prepare for the interview, candidates should practice coding challenges, review data structures and algorithms, and familiarize themselves with the required programming languages. Google interviewers also expect candidates to articulate their thought processes and solutions effectively, so it is important to communicate clearly and efficiently.

Practicing for Behavioral Interviews

Behavioral interviews are a critical component of Google L4 interviews. The aim of these interviews is to assess a candidate’s ability to work collaboratively, adapt to change, and solve problems. Behavioral interview questions often reflect on a candidate’s past experiences and how they handled challenging situations. Study Google’s core values, and prepare answers to behavioral interview questions such as, “What is the most challenging project you have led, and how did you ensure its success?” or “Tell me about a time when you had to deal with a difficult team member.” To prepare, candidates should review common behavioral interview questions, identify their experiences that showcase these behaviors, and use the STAR technique (Situation, Task, Action, Result) to effectively communicate their answers.

Google L4 Interview Experience

Round 1: Technical Interview

The technical interview is the first round in the Google L4 interview process. It generally consists of one or more interviewers asking technical questions and having the candidate write code or solve problems on a whiteboard. Examples of questions that may be asked during this round include topics such as data structures, algorithms, and programming languages. It is crucial for the candidate to be familiar with these topics and to remain calm under pressure.

Round 2: Code Review

The second round of the Google L4 interview process is the code review. In this round, the interviewer(s) will ask the candidate to review a code sample and provide feedback. The code sample is generally written in the programming language the candidate is most familiar with. This round tests the candidate’s ability to communicate technical concepts and offer constructive criticism.

Round 3: Hiring Manager Interview

The hiring manager interview is the final round of the Google L4 interview process. In this round, the candidate will meet with a hiring manager to discuss their background, experience, and skills. The interviewer may ask questions about the candidate’s career goals and what they can bring to the team. It is important for the candidate to display a positive attitude and demonstrate how their skills align with the company’s ideals.


In conclusion, preparing for a Google L4 interview requires a deep understanding of the company’s values, as well as technical expertise. It is essential to showcase your programming skills and experience effectively. The interview process varies and can be intense, but this should not deter you from doing your best.

When preparing for the interview, it is important to spend a significant amount of time reviewing programming languages and syntax. Since 70% of the workday is spent coding at Google, proficiency in coding languages and algorithms is crucial.

The L4 position is commonly awarded to new graduates or high potential individuals with 1-5 years of industry experience. The senior-level L5 position requires at least six years of industry experience as a software engineer.

Our ultimate guide provides several tips on how to prepare for a technical interview at Google. Remember to refrain from appearing arrogant during the interview and remain confident, yet humble.

In conclusion, the Google L4 interview requires a good balance of in-depth technical knowledge and conveying your ability to work well with others, along with Google’s core values. If you approach the interview process with the right mindset and adequately prepare, there is no reason why you can’t succeed.
