13) Would it be a good idea for Google to start charging Gmail users $1 per month?

This question is to check your knowledge of the google ecosystem that will take a hit, as customers will start to quit the platform due to the fee.

14) Who do you believe are Google’s main competitors? How does Google stand apart?

The Interviewer can tell if you have a firm grasp of which other businesses rules the market where Google is also present by asking you this question. This can be especially true for occupations that focus on products, such as product manager and software development positions, where the ability to outperform other businesses is a given.

An Ideal answer to this question would be – Depending on the industry, Google’s key rivals may include Microsoft, Facebook, Netflix, Waze, and several other companies. Google’s capacity to connect its services and produce a seamless cross-platform experience is one of the key differentiators. Google offers a huge variety of services, too. It encourages a level of comfort with the products and platforms that you would not necessarily experience with some of the competitors.

15) What is your favorite Google product? What would you do to improve it?

The candidate’s familiarity with Google’s services is tested by this question. Any Google product can be chosen as long as the candidate can enthusiastically discuss it and offer a pertinent recommendation.

An Ideal answer will look like this – The Google product I use the most is YouTube. For individuals who wish to offer their ideas, skills, and advice, the platform itself is tremendously empowering and engaging. I’ve personally used it a lot to research issues, learn new things, or just pass some time having fun.

If I could change anything about YouTube, I would make it possible to modify the recommended videos. This issue might be solved by giving users the option to ask YouTube to display them less similar content to a certain video.

16) How do you make sure that you and your colleagues remain accountable?

Every employer views accountability as essential. Google wants to know if you are capable of handling your responsibilities and holding yourself to an acceptable standard.

19) If you got this job, what prank would you pull on your manager?

This is a trick question meant to check both your personality and your familiarity with the workplace culture.

Given that the majority of Google employees are enjoyable to be around but pulling a joke on your manager isn’t something an employee should do instead an employee should make every effort to assist their Manager. In the end,d you never know about the daily activities that your employer engages whatever they are it must be stressful for them to handle so try to keep them happy and at peace.

20) Why are manhole covers round?

Due to the round shape of manhole covers, they don’t require rotation. There aren’t any corners to be careful with. It is also safer because a circular manhole cover won’t fall into a hole if it is turned the wrong way.

21) Assume an advertiser makes $0.10 every time an ad is clicked. Only 20% of visitors click on this ad. How many people does the advertiser need to visit the site for him to make $20?

22) Do you have an IQ of more than 130?

The worst possible response to this question would be “Yes” which is intended to test intellectual humility. Remembering your IQ score conveys a false sense of vulnerability and conceit.

23) There are 1000 wine bottles. One of the bottles contains poisoned wine. A rat dies after one hour of drinking the poisoned wine. How many minimum rats are needed to figure out which bottle contains poison in an hour?

The plan is to label each bottle with the corresponding binary number and number it from 1 to 1000. In the binary numbers written on the bottles, each rat is given a location. Take this as an example. Rat 1 indicates the first bit in every bottle, rat 2 represents the second bit, and so on. Bottle number 42 (Binary 0000101010) is poisoned if rats 2, 4, and 6 die.

To locate the poisoned bottle, we need ten rats. The binary number system was used to produce the outcome. Using Log21000, we arrive at 10.

24) How many ways are there for finding a needle in a haystack?

Your capacity for creativity and original thought will be tested by this question. There are countless possibilities for this question’s responses.

You could decide to use a metal detector, you could decide to burn the haystack at a temperature that preserves the needle while turning the hay into ashes, or you might decide to patiently go over each straw of hay, however, this could take you several months to find the needle.

25)  How would you describe AdWords to a 7-year-old?

The purpose of this question is to check your knowledge of how AdWords functions and your capacity for clearly articulating a complex feature.

An Ideal answer to this question will look like this:

Think that you have many chocolates that you want to sell and the entire universe is your friend. You crave to eat Nachos and you realize that you can trade chocolates for Nachos. You can ask them for Nachos and give them one of your chocolates because everyone is your friend. We ought to give others what we have and in exchange, they give us what we want.

Now that you are aware of how vast the universe is, how do you communicate with them without their phone number? Facebook and  Instagram are also out of available options.

Here comes into the picture of everyone’s friend Google. As a result, everyone tells Google what items they have that consumers can purchase from them. Anyone may use Google to search for anything they want, and Google will provide a list of all their friends who can provide it, along with information on how to obtain it, what the friends want, where they live, etc.

You may therefore provide Google with all the information it needs about your chocolates, and Google will display that information anytime someone searches for chocolates. Simply type “Nachos” into Google to find the Nachos you desire, and it will display all of your friends that can gift you Nachos.

Every time someone searches for something and selects one of the buddy alternatives, the friend pays Google a tiny fee for linking them. This is because Google is being kind and connecting all these pals.

The applicant must explain how their qualifications match those of Google, the employer, and the particular position they are applying for in this question. This is your time to demonstrate that you are qualified for the position and are familiar with the business instead of although it is a very crucial aspect to some, the existence of offering reasons like free meals and the chance to bring your pet to the Googleplex is not what you want to do here.

Google constantly rolls out new hardware and software. This organization might benefit from your experience as an app developer. Inform them that you want to meet with the team to explore how you can be of assistance.

33) What is your knowledge of Google’s history

Google LLC, formerly known as Google Inc. (1998-2017), is an American business that creates, produces, and distributes software across a range of technological fields. It is headquartered in Mountain View, California. Google handles more than 70% of all global online search inquiries, making it crucial to the experience of the majority of internet users.

Google initially only concentrated on its search feature, but it now provides a wide range of services, including email, software for creating documents, and more. However, it was able to offer its hardware after purchasing Motorola Mobility in 2012.

Alongside Apple, IBM, and Microsoft, Google ranks as one of the four largest corporations because of the breadth of its product line, scale, and impact on the high-tech industry. However, the success of the company is primarily due to its search engine.

For example, You had had a disagreement with your employer about a choice that would have been very expensive for the business. It was about how we would manage our employee’s travel expenses, and I offered a strategy that helped the business save roughly $1000.

For instance, If you claim that you can drink two pints of beers in 30 seconds the interviewer might want to know why that skill is relevant to their business. So give impressive information about you that is also relevant to the business like some achievement that you might be proud of but couldn’t mention in your resume.

The majority of successful people in this position not only have a willingness to work hard and learn, but they also have a great deal of passion for their job and their field of expertise.

I disapprove of Google charging for its productivity tools. Since not everyone is ready to pay for software, charging for these apps will make it difficult for them to attract a significant user base. Many users don’t want to pay for these apps because they use them daily as part of their jobs. They can experience a drop in users as a result of these fees, or they might even lose potential clients as a result of the high costs.

42) Mention what is the weight of the empire state building?

The interviewer asks this query to probe the candidate’s mental processes. The purpose of such questions is to assess the candidate’s ability to make educated guesses.

To answer this question in a google interview your technical expertise, problem-solving ability, communication abilities, and persuasiveness will all be evaluated by this question.

Start with a comparable experience to help the client relationship with the problem from that experience, and then thoroughly describe the issue at hand. Display an awareness of the needs of the client, including why they would require this solution and how it will help them. Discuss the product’s advantages over rivals as well.

49) If an advertiser doesn’t see the benefit of Adwords due to poor conversions, how would you convince them to stay on board? 

This question checks your convincing skills, problem-solving ability, and communication skills the answer to this question should be like:

I’d try to figure out why conversion rates are low initially. In situations like this, the issue is typical with the client’s website.

I can either sell them a new website or make improvements to their current one, so my strategy is rather simple. On the other side, I can create a landing page using a platform like Unbounce to check whether we generate any leads or close any sales. However, this method is best used for lead generation rather than e-commerce.

You may test to see whether your conversion tracking is effective and ensure that you are tracking every conversion you can, including phone conversions, sales, and contact form conversions. Occasionally, even though conversions are occurring because they are not being recorded, a client may not experience any benefits. You must demonstrate the effectiveness of your Adwords advertisements to them. Adwords only presents a problem when it comes to converting views, in other words. Give them statistics such as the duration of their visit, the number of pages they saw, and the bounce rate. However, go into it knowing what the issue is and how to resolve it. Even if it’s simply a test, let the client know that you identified a potential issue and offered a potential solution.

50) Could you briefly explain AdWords to someone unfamiliar with the product and online advertising?   

In this question, you will be judged on your ability to explain a challenging business challenge and find a solution. It doesn’t matter how much you know, what matters is how well you can explain it to someone else. Companies utilize Google Ads, a platform for online advertising, to advertise their goods and services on Google Search, YouTube, and other websites. Companies can also choose the type of traffic they want their advertising to bring in with Google Ads. Advertisers can tailor their budgets, and target audiences, and start or stop their advertising whenever they want with a Google Ads account.
