The Google Data Analyst interview process is in the typical 2-interview format. The interview process starts with an initial telephonic interview, called the initial screen, with a company HR or a hiring manager. Candidates who clear the initial screen are then called for the onsite round. The onsite round comprises three 1:1 interviews, with a short lunch break in between
This is the preliminary interview, largely similar to the initial screen conducted at other tech companies such as Amazon, Apple, Microsoft etc. The initial screen round lasts for about 30 minutes. Here, the recruiter asks some basic questions regarding your CV, your motivation for the role and company, and assesses your experiential and cultural fit for the company. In the course of the interview, the interviewer will also tell you about Google, its culture, the team you are applying for, and share information as to what the scope of the current job would be.
Most commonly asked questions in the initial screen
- Why do you want to pursue a career as a Data Analyst?
- Why do you want to join Google?
- Where do you see yourself ten years down the line?
- What aspects of Google's work culture appeal to you the most?
The onsite interview is the final stage of the Google data analyst interview process. It consists of 3-4 one on one interviews, each around 45 minutes long. These interviews would be conducted by a hiring manager, team manager, and developer (to determine your SQL and data analytics skills). There is a one-hour lunch break in between the interviews. Candidates can use this time to interact with a current Google data analyst to better understand the role and company culture.
Broadly speaking, three major areas are covered in the onsite round. These are:
- SQL, Excel, and Statistics
- Product Sense
- Behavioural aspects.
- Revise your SQL concepts well as it's a core focus area.
- Be familiar with Google's products as questions in the product sense section will revolve around these.
- Let the interviewer know your approach to the problem and not just the solution.
- Do not hesitate to ask clarifying questions to the interviewer.
- Keep an answer ready for the cliched "Why Google?" question by the company HR.
