Google tough interview questions can look intimidating, but they are far easier for those who truly understand the concepts and then practice implementation. Google interview questions are well-crafted to test several skills. Google is not looking for rote memorization of standard question-solving patterns, just excellent role-related skills and an in-depth understanding of the concepts surrounding them.

Top Google Tough Interview Questions and Answers

We’ll begin with some sample Google tough interview questions and answers to get a basic idea of what to expect.

Q1. How many times in a day do a clock’s hands make zero degrees with each other and overlap?

A clock’s hands overlap 22 times a day. There are 11 intervals in one hour, and the overlap happens once for every hour interval. 

Q2. You have eight balls. Seven of them weigh the same, and only one weighs heavier. Determine which one in two weighings.

Pick any six balls and put three on each side of the weighing scale. If the weights of the three-ball sets are the same, the heavy ball isn't one of these six. It's one of the remaining two balls. Now put the two remaining on the scale to see which one. However, if one set of three weighs heavier than the other in the group of six, the ball is one in the heavier set of three. Put any two of those three on the scale. If there’s a heavy ball in that measurement, you have found it. If both balls have the same weight, then the remaining ball that wasn’t measured is the heavy ball.

Q3. Explain the significance of "dead beef."

DEADBEEF refers to 0xDEADBEEF and is a hexadecimal value used in debugging in the mainframe/assembly days. IBM RS/6000 systems use it, Mac OS on 32-bit PowerPC processors uses it, and the Commodore Amiga uses it as a magic debug value. On Sun Microsystems' Solaris, dead beef marks freed kernel memory. 

Q4. Explain a database in one sentence to your eight-year-old nephew.

A database is like a person who remembers lots of information about lots of things and gives other people that information when they need it. 

Q5. Why are maintenance hole covers round?

Round maintenance hole covers don’t accidentally fall into the hole and are easier to manufacture. They require no alignment as there are no sides/corners in the round shape. This makes the heavy maintenance hole covers easier to put back on without hassle.

Sample Google Tough Interview Questions for Practice

Here are some Google tough interview questions. Ensure you can solve them before your interview:

  2. Would it be good for Google to charge Gmail users?
  3. How would you explain the importance of HTML to your grandmother?
  4. How many ways are there to find a needle in a haystack?
  5. What changes will happen in the digital advertising space in the next few years?
  6. An advertiser makes $0.10 every time an ad is clicked. Only 20% of visitors click on this ad. How many people need to visit the site for the advertiser to make $20?
  7. What would you spend your time on if you didn’t have to work?
  8. Explain the internet to a person who has no clue what it is.
  9. If you had to remove ads from YouTube, how would you continue making money from the platform?
  10. Which has a significant advertising potential between a flower shop and a funeral home?
  11. How much will you charge to wash all the windows in the city?
  12. What day is today if the day before, the day before yesterday, comes three days after Saturday? 
  13. How would you solve homelessness in downtown San Francisco?
  14. How can a man accurately predict the exact score of every football game before it begins?
