Google Backend Engineer Interview Process
In this Google backend engineer interview preparation guide, the general seven-step interview process is illustrated in the above figure. However, each step, particularly technical rounds, may have multiple rounds with experts in specific backend technologies.
This Google backend engineer interview preparation guide focuses on the technical phone and onsite or virtual interview rounds. Let us look at the interview process.
- Resume Screening: The resume is the first contact with Google. Since the firm receives thousands of applications for a job, Google uses an Applicant Tracking System (ATS) to scan for keywords. Write a professional resume to meet the backend engineer role criteria to see if your experience aligns with the role’s requirements.
- Recruiter Call: If your CV is selected, then expect an initial call from a recruiter who may be from HR. Be prepared to discuss the role, your background, experience, and other details.
- Technical Screening: Expect one or two calls from a technical expert who will assess your coding and problem-solving skills, and your ability to write and edit algorithmic problems in a shared document.
- On-site and Virtual Screening: Expect 4-6 technical interviews either through a virtual environment or in-person. An AI-powered coding environment will be created, and you can access it through a computer. Questions will be on coding, algorithms, and specific Google technologies. The computer camera is used to track your eye movements, keystrokes, and if you change screens, refer to online help, use adjacent devices, or cheat in other ways. You are ejected from the interview if you repeat any untoward behavior. Interview rounds can cover coding ability, system design, and behavioral skills to see the cultural fit.
- Hiring Committee Review: Department technical head and HR managers will conduct a final interview. Feedback and test scores from all interviewers are reviewed and compared with the performance of other candidates. A final decision will be made to hire or place on the wait list.
- Team Matching: If the hiring committee approves, there may be additional interviews with department and team managers to find the best fit for your skills and interests.
- Salary Negotiation: Congratulations on reaching this step. The recruiter will discuss compensation and make an offer.
