Google stopped asking these 7 questions because they were so difficult

Do you reckon you could answer them?

Google is one of the most prestigious companies to work for in the world.

If you're lucky enough to bag a job interview there, you'll need to be prepared. Google is renowned for its odd hiring tactics.

Interviewers' questions aren't easy. Bosses ask some of the most challenging – and bizarre – around. Candidates can't get away with saying, "search engines are my passion", let's put it that way.

Many of the tech giant's previous questions have been posted online. And now we've learned through Business Insider that a number of them are so peculiar that they've been banned altogether.

Future Google employees, take note. You won't be asked any of these...

(We've included some answers at the bottom)

Why are manhole covers round?

You have two eggs and access to a 100-story building ...

Google continued: "Eggs can be very hard or very fragile, which means they may break if dropped from the first floor or may not even break if dropped from 100th floor.

"Both eggs are identical. You need to figure out the highest floor of a 100-story building an egg can be dropped without breaking. The question is how many drops you need to make. You are allowed to break two eggs in the process."

You need to check that your friend Bob has your correct phone number, but you cannot ask him directly ...

Google asked: "You must write the question on a card and give it to Eve, who will take the card to Bob and return the answer to you.

"What must you write on the card, besides the question, to ensure that Bob can encode the message so that Eve cannot read your phone number?"

How many times a day do a clock's hands overlap?

Design an evacuation plan for San Francisco

Explain the significance of 'dead beef.'

Every man in a village of 100 married couples has cheated on his wife ...

Google had this tricky scenario to dissect: "Every wife in the village instantly knows when a man other than her husband has cheated but does not know when her own husband has.

"The village has a law that does not allow for adultery. Any wife who can prove that her husband is unfaithful must kill him that very day. The women of the village would never disobey this law.

"One day, the queen of the village visits and announces that at least one husband has been unfaithful. What happens?"

Answers

Manholes:

This one is the least weird. It's because circular covers can't fall into its own opening. A square one, at certain angles, could plummet into a sewer-y abyss.

Eggs:

Look, this is just too hard. Just make an omelette.

Bob's phone number:

Since you're just 'checking,' just as him to call you at a certain time. If he doesn't, he doesn't have your number.

Clocks:

From Tech Interviews : "This implies that the first overlap happens after T = 12 / 11 hours (~1:05 am). Similarly, the second time they overlap, the minute hand would have completed two more laps than the hour hand. So for N overlaps, we have T = T/ 12 + N. Thus, the hands of a clock overlap 22 times a day."

San Francisco evacuation:

This is more about the interviewer seeing how the interviewee would attack a problem – there's not really a set answer. You should start by asking, "What kind of disaster are we planning for?"

Dead beef:

Nothing to do with cows. "Dead beef is a hexadecimal value that was used in debugging back in the mainframe/assembly days because it was easy to see when marking and finding specific memory in pages of hex dumps. Most computer science graduates have seen this at least in their assembly language classes in college and that's why they expect software engineers to know it," said BI .

Adultery:
