2. Technical Phone Screen(s)

The technical phone screen is your first real technical challenge in the Google interview process. The interview is conducted via video conferencing tools like Google Meet.

During this session, an interviewer will present a coding problem, often of medium difficulty, which you are expected to solve in real-time. You'll share your screen to write code, discuss your approach, and address any questions.

While the focus is on technical skills, you may also encounter questions about your background, experiences, and motivations. For instance, you might be asked, "Tell me about a recent project you worked on.

3. On-site Interview

Following a successful Technical Phone Screen(s), the next step is the onsite interview. Depending on your selected location, you will be invited to visit a Google office, where you'll spend an entire day.

This phase typically involves 4-6 interview rounds and covers the following areas:

  • Coding interviews: These rounds focus on data structures and algorithms, testing your ability to solve complex problems efficiently. In most interviews, you'll be expected to write code on a whiteboard, though some locations may offer Chromebooks with an interview app for coding in your preferred language.
  • System design interviews: If you're applying for a Level 5 position or above, you'll also face one or two system design interviews. These are more complex and involve designing large-scale systems. You'll be asked to demonstrate your ability to think through architecture, scalability, and the overall design of a system.
  • Leadership interviews: For candidates applying for management positions, such as the Engineering Manager role, leadership interviews will be included. Expect behavioral questions that explore your leadership experience, conflict resolution, and decision-making skills.
  • Lunch interview: While not a formal interview, you'll have lunch with a fellow Google engineer during your onsite visit. It’s a great opportunity to ask questions about the work culture, team dynamics, and life at Google.

4. Offer

After completing the onsite interviews, the hiring team at Google carefully evaluates all candidates based on their performance and overall fit for the role. If you are selected, you will receive a formal offer letter. This letter will include detailed information about your compensation package, benefits, and other job-related specifics.

While Google generally offers a very attractive package, there is room for negotiation if the initial offer does not align with your expectations. Be sure to thoroughly review the offer and discuss any concerns you may have with the recruiter or hiring manager.

Once you accept the offer, the final step is to complete the onboarding process. This will involve administrative tasks, as well as introductions to your team and the tools and systems you'll be using.

What Questions Should You Expect in the Google Interview?

When preparing for a Google software engineering interview, you must understand the types of questions you’ll face. Here are a few common types of software enginnering interview questions:

Example questions:

  • “Implement an algorithm to find the longest substring without repeating characters.”
  • “Given a binary tree, write a function to check if it’s balanced.”
  • “Write a function to perform a depth-first search on a graph.”

2. System Design Questions

In these questions, Google evaluates your ability to design large-scale systems. The goal is to assess how well you approach system-level problems, how you prioritize different components, and how you ensure reliability and scalability.

Example question:

  • "Design a web-based file storage system like Google Drive, and explain how you would handle concurrency, storage, and scalability."
  • "Design a URL shortening service (like Bitly)."
  • "How would you build a recommendation system for a large e-commerce platform?"

3. Behavioral Questions

In addition to technical questions, Google is also interested in assessing how you fit within their culture. Behavioral questions typically focus on your past experiences, soft skills, collaboration, and problem-solving abilities.

Examples include:

  • “Tell me about a time you had to deal with a challenging project.”
  • “Describe a situation where you had to resolve a conflict within your team.”
  • “Give an example of when you took initiative and led a project.”
