There isn’t a single person we know that wouldn’t want to work for Google. I mean it’s Google! Most people don’t even get a chance to interview with them and now you do. How do you even begin to prepare for one of the most important (if not the most important) interviews you will ever have in your lifetime? We have determined the following findings based on the feedback of over 70 Google Product Managers and Product Manager candidates that have interviewed for a Product Manager role at Google as either a Hiring Manager or Product Manager candidate. For your benefit, we have broken our findings into 3 sections.
- How to Prepare for a Google Product Manager Interview
- What to Expect
- What Not to Expect
HOW TO PREPARE FOR A GOOGLE PRODUCT MANAGER INTERVIEWThe first thing we recommend is reviewing tech blogs, such as Stratechery. This is something that you can do right now whether you have an interview scheduled with Google or not. If your aim is to work at Google, make this website and the content within it a part of your weekly reading ritual.
What to ExpectThere are 6 major components to the Google Product Manager (PM) interview:
- Product Design
- Culture Fit
PRODUCT DESIGNGoogle Product Managers put users first. Product Managers are obsessed with providing the best user experiences. Think about all the Google Products you use and take for granted every day and imagine life without them. At Google, this process begins with customer empathy and a passion for products, down to the most acute details. A wireframe can be sketched just to convey an idea to a designer.
Product Design Sample Questions:
- How would you improve Google Maps?
- How would you reduce Gmail storage size?
- How would you improve the restaurant search?
- What’s your favorite Google product? What do you like or dislike about it?
- If you were to build the next killer feature for Google, what would it be?
- You’re part of the Google Search webspam team. How would you detect duplicate websites?
How to Prepare for the Product Design Questions:
- Practice and envision leading design discussions using a framework. (Need a framework? Try CIRCLES Method: http://qr.ae/i6kRM).
- Begin with possible personas and detail use cases.
- Prioritize use cases and brainstorm solutions. Many Product Manager candidates often make the mistake of suggesting solutions that are incremental or derivatives of a competitor’s feature set. You don’t want to end your Product Manager interview with Google this way. The Product Management Hiring Panel at Google is evaluating your creativity, and they place a big emphasis on big ideas (aka “moonshots”).
- Impress and inspire them with unique, compelling ideas.
- Drawing wireframes on a whiteboard will help illustrate your ideas.
- To practice, download a wireframing tool like Balsamiq.
- Study popular web and mobile design patterns for inspiration.
ANALYTICS AND DATAGoogle Product Managers are fluent in the language of numbers to define the right metrics. Google Product Managers make their point by communicating their analysis. They can decipher and make decisions from A/B test results, go so far as to write SQL queries, and even run scripts to extract data from logs. In essence, they don’t mind getting their hands dirty and doing whatever is required to prove their point.
Analytics and Data Sample Questions:
- How many queries per second does Gmail get?
- How many iPhones are sold in the US each year?
- As the Product Manager for Google Glass ‘Enterprise Edition,’ which metrics would you track? How do you know if the product is successful?
How to Prepare for the Analytical Questions:
- Prepare for estimation questions such as, “How many queries per second does Gmail get?”
- Get well-versed in product launch metrics and A/B testing, including interpretation of results.
STRATEGYGoogle Product Managers are business leaders. As a result, they must be familiar with business issues. It’s not necessary for Google Product Managers to have business experience or formal business training. However, they do expect you to pick up business intuition and judgment quickly.
Strategy Sample Questions:
- If you were Google‘s CEO, would you be concerned about Microsoft?
- Should Google offer a StubHub competitor? That is, sell sports, concert, and theater tickets?
- Use a framework to structure your strategy discussions. If you’re not familiar with strategy or frameworks, Porter’s Five Forces is a good start.
CULTURAL FITGoogle Product Managers lead and influence effectively, have a bias for action, and get things done. Many Google Product Managers go on to become CEOs of their own companies, as well as other companies. Having said that, being smart isn’t enough; YOU HAVE TO FIT IN WITH THIS CROWD. Google prides itself on their ability to get things done as an organization. This is one of the most difficult criterias to fulfill and one of the reasons why Google is so cool to work at. You are going to have to show that you are smart enough to hang with the best of the best, and fit in with the rest. It’s a balancing act, but absolutely necessary to weed out all the people that Google DOES NOT WANT.
Culture Fit Sample Questions:
- Why Google?
- Why Product Manager?
How to Prepare for the Culture Fit Questions:
- Understand what it means to be “Googley” by reading Google’s corporate philosophy.
- Review Google‘s Android design principles.
- Optional readings:
- Google‘s visual asset guidelines and Steven Levy’s 2007 (but still useful) article on the Google APM program
- Another optional, but more in-depth (and recent) perspective, read Steven Levy’s “In the Plex: How Google Thinks, Works, and Shapes Our Lives.”
TECHNICAL QUESTIONSGoogle Product Managers lead product development teams. Leading effectively means Product Managers have influence and credibility with engineers. At the final round (aka onsite) interview, a senior member of the engineering team will evaluate your technical competence. Be prepared for whiteboard coding questions at the onsite interview.
Technical Sample Questions:
- Write an algorithm that detects meeting conflicts.
How to Prepare the Technical Questions:Coding questions are unlikely during the phone interviews, but if you are invited to an on-site interview, you must prepare for programming interviews. The technical interviewer does not expect your programming syntax to be perfect, but you should have sufficient mastery of technical concepts so that you can participate in technical discussions and help make technical trade-offs. I would recommend going over computer science fundamentals and practicing a couple of coding questions. One of my favorite resources is How to Ace the Software Engineering Interview. Also be prepared to describe key technologies including search engines, machine learning, and MapReduce.
BEHAVIORBe prepared for behavioral interview questions such as, “Tell me a time when you had to influence engineering to build a particular feature.” Google Product Manager interviewers are relying more on behavioral interview questions in recent months.
What Not to ExpectBrain teasers, such as logic puzzles, are rarely used in today’s Google Product Manager interviews. Google‘s HR department found a low correlation between job performance and a candidate’s ability to solve brain teasers.
Examples of brain teasers include:
- I roll two dice. What is the probability that the 2nd number is greater than the 1st?
- What’s 27 x 27 without using a calculator or paper?
ADDITIONAL INTERVIEW QUESTIONS
- Tell me about a Consumer Product you like
- Apple music has curatoratorial driven playlists while Spotify is more algorithmically driven. What do you think about that?
