1. There are infinite black and white dots on a plane. Prove that the distance between one black dot and one white dot is one unit. 2.Suppose that there is a building with 100 floors. You are given two identical eggs. The most interesting property of the eggs is that every egg has its own “threshold” floor. Let’s call that floor N. What this means is that the egg will not break when dropped from any floor below floor N, but the egg will definitely break from any floor above floor N, including floor N itself. 3. Prove to me that you're honest – in one minute. 4. How many steps did you come across in this building while you were on your way to this questions?

Answer:
Maintaining a diary is generally a very good habit. Moreover, one can always check facts looking back, remember events, find an outlet and effectively document one’s life this way. Also, some people even name their diaries and address them like an imaginary friend.
A personal journal is a private possession. In other words, this diary usually is just for you and it’s not for public reading, so one can write liberally. But for the benefit of the readers, we’d like to show you all how is a diary entry generally written. What we are laying down here are good practices that one can inculcate while writing their diary entry.

Based on the Quora thread: What is the toughest question ever asked in any interview?
Obviously, interviewing is important. It’s your chance to get to know the candidate and really decide if they are what you’re looking for in the position.
That said, some organizations have taken it too far, asking impossibly difficult questions to see how someone can handle pressure. Google, for instance, was infamous for asking ridiculously tough brain teasers, only to put an end to such questions a few years ago.
So, what are some of the hardest interview questions ever asked?

A question asked during an interview for a technology analysts role at Goldman Sachs. If you know the answer, you probably should be working for NASA.
2. Can you tell me the 15 errors in the code you just created?

The following scenario unfolded at an interview with one of the computer giants:
A candidate for a software engineering position walked into an interview and was asked to write a program that prints “Hello World” in any language. The interviewer glanced at the code and told the candidate he had five minutes to find 15 errors in the code.
The candidate couldn’t do it and was rejected for the job.
3. How can you drop two eggs the fewest amount of times, without them breaking?

A rather long-winded question, asked by a Silicon Valley engineering company. Here’s the full question:
Suppose that there is a building with 100 floors. You are given two identical eggs. The most interesting property of the eggs is that every egg has its own “threshold” floor. Let’s call that floor N. What this means is that the egg will not break when dropped from any floor below floor N, but the egg will definitely break from any floor above floor N, including floor N itself.
For example, if the property of the eggs is that N equals 15, those eggs will always break on any floor higher than or equal to the 15th floor, but those eggs will never break on any floor below floor 15. The same holds true for the other egg, since they are identical.
