What are the best logical questions for an interview?

I have faced so many logical questions during my job interview, I will tell you the best one

Question: There are 9 black socks and 9 white socks mixed in a bucket, and the bucket is in a dark room, you can't recognize the colors. Therefore, you must wear a pair of socks that must be white or black, not black and white. What is the minimum number of socks you can photograph for an absolute pair?

Answer: 3. so that there is the possibility of getting a pair of white or black

ABCD x 4 = DCBA.

What are the values ​​of A, B, C, and D? Values ​​are
between 0 and 9 and each is different.

Just check it once.

Karan Dharamdasani's answer to What's the best interview question?

A Japanese multinational interviewed me (I can't reveal the name) and they asked me how many riddles I found interesting.

Question 1: There is a room in which there are 3 electric bulbs. The room has only one door and it is locked, which means there is no way to look in or enter the interior other than the door. Right outside the room there are 3 switches where each switch is connected to a light bulb. Now your question is that you are allowed to enter the room only once, so how can you determine which light bulb is connected to which switch?

Answer given by me:

Only on the first switch for 5 minutes

A Japanese multinational interviewed me (I can't reveal the name) and they asked me how many riddles I found interesting.

Question 1: There is a room in which there are 3 electric bulbs. The room has only one door and it is locked, which means there is no way to look in or enter the interior other than the door. Right outside the room there are 3 switches where each switch is connected to a light bulb. Now your question is that you are allowed to enter the room only once, so how can you determine which light bulb is connected to which switch?

Answer given by me:

Just turn on the first switch for 5 minutes and then turn it off. Then just flip the second switch and walk into the room. Now the bulb that is connected with the second switch will light up and just check the remaining two bulbs by touching them, the one that is hot, the one that would be hot should connect with switch one and the remaining bulb will connect with the switch. third.

They also asked the number of puzzled as

Question 2: Divide a cake into 8 equal parts using only 3 knife cuts.

Answer given by me:

Just make two cuts vertically by dividing the cake into 4 equal parts (a cross) and make one cut horizontally that will divide the cake into 8 equal parts.

Another interview experience was with One US Company (Can't reveal the name), they even took a round especially for Puzzles ... There were some standard puzzles, some were easy and some were even the hardest to solve.

Question 3: You are given 1, 2, 6 and 7 with +, -, * and / how would you do 17 (You cannot repeat numbers and you cannot repeat operations, but you cannot skip one or more operations as you can only use +, - or +, -, *)

Answer :

(6-1) * 2 + 7

Question 4: You are given four 12,8,5 and 1 liter bowls. The 12-liter bowl is full of milk. How would you divide the milk between 4, 4 and 4 liters in 12.8 and 5-liter bowls?

Answer:

12 8 5 1

12 0 0 0 // Initially the 12-liter container is full

4 8 0 0 // pour 8 liters from a 12-liter bowl into an 8-liter bowl

4 3 5 0 // then the 5 liter bowl filled from the 8 liter bowl

4 3 4 1 // then pour 1 liter of 5 liters into a 1 liter container

4 4 4 0 // then pour 1 liter into an 8 liter bowl

Question 5: You are given 8 balls of identical appearance, one of which is heavier. You are also given a balance. How would you determine which ball is heavier with a minimum comparison number?

Answer:

Initially I told them that it would take 3 comparisons because if you divide the balls into groups of 4 and 4 and then the weights (1 Compare) you will end up with a group of 4 balls. Then divide again into 2 and 2, then compare (comparison 2) and then 1-1 (comparison 3). Then they asked me if there is any other way to optimize. I got stuck and started to think and answered that instead of making 2 groups we can make 3 groups of 3,3 and 2 and weigh 3 and 3 balls (1 Comparison) and then again in 3 Balls we make 3 groups of 1 ball each and weigh them (2 Comparison).

There were more riddles, even they not only asked this kind of riddles, but they also asked riddles related to programming languages, since I am from Computer Science and Interviewed for the position of Engineer.

Edit: As Pankaj pointed out, there was an ambiguity in the last question.

1. You have 12 coins. One of them is bad and is heavier or lighter than the others, you don't know which one. He has a jeweler's scale; no coins will be weighed; There are only two sides that will balance or not, depending on the coins you put on each side.
What is the minimum number of weighings or balances with which you can find out the bad coin and also know if it is heavier or lighter than the others?

2. Roger is picked up from work by his wife at exactly 4 pm every day.
One day Roger finished work half an hour early and started walking to meet up.

2. Roger is picked up from work by his wife at exactly 4 pm every day.
One day Roger finished work half an hour early and started walking to meet his wife. He met his wife on the way and they drove home together. When they got home, Roger noticed that they had returned 10 minutes earlier than usual.
How long did Roger walk?

3. There are no timekeeping mechanisms (clock, watch) in a room. There are 2 candles in the same room. Each candle when lit, has its wax completely depleted in exactly 1 hour. How will you track the 45 minute pass? (NOTE: The candles do not burn proportionally, that is, the consumption of half the candle does not indicate a step of 30 min.)

4. Four people need to cross a dark river at night. They need a torch to cross the river and at the same time only 2 people maximum can walk on the bridge. They have only one torch. The speed of each person crossing the river is different. They are 3 minutes, 4 minutes, 10 minutes and 20 minutes respectively.
What is the shortest time needed for the four of them to cross the river?

5. Consider a stick of length 1. Pick two points uniformly at random on the stick and break the stick at those points. What is the probability that the three segments obtained in this way form a triangle?

6. Sudeep was traveling by train one night. It was late, but he wasn't sleepy. A math teacher was sitting across from him and they had been chatting for a while. A few minutes ago, the teacher had asked: “There are three men.
Can you tell me their ages if I tell you that they are the same age as you and that the product of their ages is 2450? ”. After thinking long and hard about it, Sudeep replied, "No, it's not possible." The professor replied, “Of course it is not. I know, but let me tell you that if I tell you that I am younger than the oldest of men, you will be able to find out their ages and mine.
"How old are the teachers?

7. I am looking for a number that consists of 9 digits so that digits 1 through 9 appear only once. The number is divisible by 9, but when the rightmost digit is removed, the remaining number is divisible by 8. Again, when the rightmost digit is removed, the remaining number is divisible by 7. This property holds to the last remaining one-digit number that is divisible by 1. What is the original 9-digit number?

8. I was sitting with my friend Samir and his grandfather last week, and the topic of birthday surprises came up (we usually talk trash). Daji mentioned that one of the biggest surprises he's had involved his grandfather, who happened to have the same birthday as Dadaji. One year the family was celebrating this double birthday, and during the events, Dadaji proudly mentioned to his grandfather that not only had he just turned the last two digits of the year he was born, but that it was also a prime number of years, and each of the two digits that make up his age was also a prime.
Dadaji was understandably surprised when the older man thought for a second, turned to him and told him that the same thing had just happened to him! In what year did this occur, and how old had Dadaji and his grandfather just turned? (Hint: be realistic)

9. Each number from 1 to 10 ^ 10 is written in American style words and they are arranged alphabetically ... Do you find the first odd number in the list?

10. You have 25 horses, a race track where 5 horses can ride at the same time. You don't have a stopwatch. In how many minimum races can you determine the 3 best horses?

Interviewer: Okay Harshit, let me puzzle you now. Are you ready for this?

Me: Sure sir (with a confident smile, but my heart was beating like hell because you never know if that same riddle could decide your fate).

Interviewer: Suppose you are given 'n' number of eggs and each egg has a threshold value of say 'm', where the threshold is the number of floors in a building after which it will break.

Me: Okay (with a poker face: Wohoooooo !!!! I know this one, this is the famous egg puzzle ... I have you Mr. Interviewer :))

Interviewer: For example, if the eggs have a threshold value of say 10, then th

Me: Okay (with a poker face: Wohoooooo !!!! I know this one, this is the famous egg puzzle ... I have you Mr. Interviewer :))

Interviewer: For example, if the eggs have a threshold value of, say, 10, then these eggs will not break when dropped from any floor that is <10 and will break when dropped from all other floors in the building that are > = 10.

Me: Okay (same poker face, actually with a more confused look so that it feels like I've asked you for an amazing puzzle)

Interviewer: So you need to calculate the minimum number of eggs needed to identify your threshold value. Since there are 100 floors in the building.

Me: Ohkeyyy… (Now I was really confused because I wasn't sure if I had asked the same puzzle or is it just me? It didn't seem like the same puzzle…)

Interviewer: (I have you Harshit… .;))

// After some reflection and reconfirming to myself that I can't treat it as the same puzzle ..

Me: 1 (I think I nailed it;))

Interviewer: What ?? Can you explain please? (This guy screwed up this last piece of cake)

Me: Sir, I would drop an egg starting from the first floor, bring it back, and do the same process sequentially until the egg hatches, which will determine the threshold value. (Got it sir :) forgot to mention in the puzzle that I couldn't reuse the egg)

// We both laughed at this ...

Result: selected.

Although this was not only the reason, but the experience was incredible;)

I have worked for about 10 companies and they have interviewed me about 30 times and these are the most common.

"Tell us about you"

This should be a short and tall overview of the package you are selling. for example: you.

“I have been doing software development in all fields for almost 20 years. My first experience with the software was at the age of 12 looking and putting sprites in my room and I have loved it ever since. "

"Where do you see yourself in 5 years?"

"Sitting in your chair" <- this is a funny one that I used to joke about until I was really old. Now i say

"Doing the same things that I have always done and loved"

"Where do you see yourself in 5 years?"

"Sitting in your chair" <- this is a funny one that I used to joke about until I was really old. Now i say

"Doing the same things that I have always done and loved"

Usually I expand on this because I hate political nonsense in my field. I am constantly approached to be a software administrator, but tbh, that's not my bag. First, for every 10 engineering positions there is 1 managerial position. Second, the longer you're away from software, the more those skills will atrophy. I've seen it over and over with managers. I don't want to be that guy. Practical coding is a must. Technical leadership is as high as I want to be at this point in my career.

"What is your greatest weakness?"

A coworker bragged about this one and it works but it's not honest to me so I only used it once. It's pretty good, but I generally give the latter because it seems more genuine.

"I am relentless" <- also works as a fortress

My answer is to be frank. I will continue in my field in any way, whether you hire me or not. "I am weak with algorithms." I usually expand on this by saying that I have coded technical documents before, but do not invert binary trees during my daily activities. It's silly to think that. I have also written a TON of KPIs for dashboards.

"What is your greatest strength?"

"I'm relentless" <- again. It can also work as a weakness, but I try to avoid this canned answer.

I generally state that in my field, I have a proven track record of adaptability and stay ahead of the curve in terms of technology.

"Do you have any question for me?"

Depending on the rounds of interviews, ask at least one question about what they envision you doing at their company. You need an idea of ​​their expectations of you there.

Ask about your tech stack.

How old is the base code?

Are you agile? waterfall?

release cycles?

Anything to understand your daily activities.

If you are in round 2 or 3 of the interview process and they ask this question again, I would say that all of your questions were answered by (insert name of previous interviewers) and anything else will be answered once you look under the hood .

"Why our company?"

This I rarely see unless it is a startup. If you "REALLY" want this startup, I hope you see a future with it and say it as such. For example: This looks amazing, and I imagine you guys are going to be the greyhound bus super or something. I only got this question early in my career. Today, you have to introduce me to your company. I've seen it all. Startup, Fortune 5, and anywhere in between. If you are really senior and in high demand, this question is rarely asked.

Beyond these questions, there will be technical questions related to your field. I've seen some crazy questions when opening a job for the first time. Avoid interviews if the position has just been opened and the company is medium in size. They will ask some stupid questions that no one knows, and then back off once no one can answer them. Usually after a week, they'll set the bar a little lower. Unfortunately, they usually pass a person who was a near-perfect fit and settle for someone mediocre just to fill the seat.

Just my observations.

Generally, the interview questions depend on the domain you are applying for.

These are the basic questions that are asked in a job interview:

  1. tell me something about you

Don't tell all the details of yours. Give your answer shortly.

  1. Why should I hire you?

Respond according to the requirement of the company.

  1. What salary do you expect?
  2. Emotional questions can be asked.

Emotional questions are asked to check mental stability.

  1. Questions related to checking for mental stability that you can work under pressure or not.
  2. How long will you work for us?
  3. Why do you want to work in our company?
  4. Give me an example of your believe

This happened to me at my off-campus job interview at wipro.

Now it was my turn and it was around 12:35 am (Nov 9, 2015) and I was completely exhausted after clearing

All rounds of GD and aptitude testing.

I was waiting for this since 9:00 am (November 8, 2016)


I entered the room and greeted the interviewer "Good morning" sir (That guy
looked at me harshly)


Interviewer: Sit Harsh


Me: thank you sir


Interviewer: He asked me about my project from last year and some other technical things from my field (ohhh, I forgot to tell you that I was studying Engineering in Electronics and Communications).

Everything was fine so far.


Interviewer: GET OUT (I mean, what is this guy throwing at me?)


Interviewer: stay outside when I call and then just come in


Almost 5 minutes passed, I knew the time perfectly because every minute for me was like an hour.


Then the bell rang and the peon called me.


Interviewer: Harsh, come in
. Sit down. Tell me what is the difference in the room now after 5 minutes than before.
(At this moment I was dumbfounded, I was like what this person is asking me)

IN MY MIND: I checked the desk thoroughly, scanned the wall, looked at the papers randomly scattered on the table ..
Then after checking all the things correctly, I replied

Me: Sir, before we went out the wall clock was showing 12:47 am (it was digital so I know the exact time) and now it shows 12:56 am, it is the only difference I see here.

Interviewer: (a professional smile)
Thank you hard, you can go now.

Me: Thank you sir (ohhhhh my gosh the butterflies just stopped on my belly)

Result: selected

First, don't be put off by this question. I have seen many HR companies use this as a tactic, mentioning the many applicants they are considering, when the reality is that they have none. What the employer wants is for you to answer the question that you currently cannot. Why should they hire you?

Here's a mad libs script, edit it however you like.

"While I am not aware of the skills of the other candidates you are considering, I believe that my ability at _____ will benefit you at _______."

Follow up with a good example of how you've accomplished that goal. If you've done your research, you can try:

Es una respuesta vaga porque el entrevistador hace una pregunta vaga.

Basándome en mi propia experiencia, ¡aquí hay algunas preguntas que me hicieron cuando era más fresco en la universidad!

Entrevista en el campus de 99acre (dot) com

P. Tiene 9 botellas del mismo tamaño, 8 de las 9 botellas tienen el mismo peso, pero una botella pesa un poco menos. ¿Cómo sabrá qué botella pesa menos si tiene una máquina de pesas india en la que puede pesar botellas solo 2 veces?

Esta pregunta tiene como objetivo descubrir su capacidad lógica y de razonamiento para que pueda calcular los problemas laborales de la vida real.

Mi respuesta después de unos minutos de trabajo duro en una página que proporcionaron.

I replied:

Put 3 bottles on the left and 3 bottles i

Based on my own experience, here are some questions I was asked when I was cooler in college!

99acre (dot) com campus interview

Q. You have 9 bottles of the same size, 8 of the 9 bottles have the same weight, but one bottle weighs a little less. How will you know which bottle weighs less if you have an Indian weight machine that can weigh bottles only 2 times?

This question aims to discover your reasoning and logical ability so that you can calculate real life work problems.

My answer after a few minutes of hard work on a page they provided.

I replied:

Put 3 bottles on left and 3 bottles in right hand side of weight machine. If both are equal than

Again put 1 one left side and 1 on right side, if weight is same then the the remaining bottle has lesser weight than all other 8 bottle.

Interviewer: great!! You must be having prior idea of this!

Me: yes I just calculated this during rough work and that's what a manager is expected to do. Fast decision and calculated risk.

Interviewer: you are in!!

I. Once my teacher told me about a girl who gave an interview for a realy good post.

The most logical question was....

How many times you slept with a male?

She answered..

Many times I can't remember because when I was a child I used to sleep with my father some time my brothers, so I can't say how many times I slept with a male?

She got selected.

II. The recruiter put a gulabjamun (an Indian sweet) in a cup and covered it with a plate and asked the candidate to eat it without touching the plate.

Then this happened .....

Candidate -Where is the gulabjamun?

Recruiter -in the cup.

Candidate, how?

Recruiter -I put it, in front of you.

Candidate -I did not see.

Recruiter, but I did.

Candidate - no, you didn't.

Recruiter: I did.

Candidate -I don't believe you.

El reclutador retiró el plato para mostrárselo y el candidato se comió el gulabjamun.
