## Probability Interview Questions

Preparing for questions on probability is important for the TCS Ninja exam. For example, the question might be focused on the seating arrangement of a group of people. The group might have a specific number of women and a different number of men. Now we have to find the probability that there is at least a given number of men between two women. In such a type of a question, we have to find the different scenarios that can happen and the number of ways the sitting arrangement can be possible in each such scenario. The total number of such different seating arrangements will give us the required value as asked in the question. It is important to remember that the question can become more complex if the number of women is increased from 2 to a different number. This is because in such a scenario, the number of men that can be arranged in between the woman is also increasing. We have to carefully apply the formulas of permutation and combination in such a type of scenario and solve the answer accordingly. I was comfortable in questions on permutation and combination but I was taking some amount of time to solve this type of problem. So I knew I had to practice such types of special case problems more. I made it a point to practice such problems from various different types of scenarios so that I was able to solve these problems in the limited time during the TCS Ninja exam. I did not want to get stuck in a particular question during the exam.

## Number Series Questions

The TCS Ninja exam might also contain questions from the number series. For example, the price of a product may be given in the form of a series that is increasing by a particular variable daily. The question might provide us with the price of another product in the form of a series. Then we will have to find at what point of time in the future will the price of the two products be equal. In such a type of a problem, we will have to apply the formulas of permutation and combination and sometimes might also have to apply variable values to see the results iteratively. By solving the two different equations for the products, we will be able to find the day and date on which the prices of the two products will be the same. Sometimes we can identify what kind of series we are dealing with just by looking at the equations. We can accordingly predict in such cases when the two equations might be equal. In some other cases, the equations are often complex with complicated series embedded within them. Such types of series may take more time to solve. So I made sure I practice various different kinds of such problems. I wanted to be able to solve all such kinds of problems related to arithmetic series at a rapid pace during the TCS Ninja exam.

## Arithmetic Questions

A particular type of problem that is important for the TCS Ninja exam is related to remainders. For example, the question will ask us to find the remainder of a product of three or four different numbers when it is divided by a particular number. For such types of problems, we need to be aware of how to find the remainders between different numbers. I was aware how to Solve different problems related to divisibility of numbers. When it came to finding the reminders, I noticed that I was sometimes taking more time when the numbers were large. Being able to effectively handle such kinds of problems, I needed more practice when the numbers were at least three to four digits in length. The remainder theorem is especially helpful to apply in such cases. How much time should I allocate in the exam to this type of problem? I asked myself. I kept on struggling with this type of problem, but I really did not want to lose marks. I did not want to lose the opportunity to be a part of my dream organization. I knew the TCS interviewers would assess every analytical ability of the candidates. Hence taking the TCS assessment exam without preparing completely was a risk. There is no alternative to hard work and lots of practice. I made sure I was aware of all the best resources available and practiced a lot. Even if I was weak in something I did not want it to come as a surprise to me during the actual exam.

## Time and Distance Problems

It is important to be able to solve time and distance related problems for the TCS Ninja exam. The problems might be related to a road network. There might be different cities which are connected to each other by road network. The problem might mention some cities can be reached only from other specific cities. The problem might also provide us with the distance between different cities. Finally, the question will ask us what is the shortest distance between two different cities? To be able to solve such type of problem, it is important to have a schematic representation of all the information that is given to us. When we have a schematic representation, it becomes easy for us to interpret the data. We will be able to quickly see what is the distance between two cities. This will allow us to fill in any hidden information that the question might have had. I tried my best to schematically represent any information given in such types of problems. I knew that time was important in the TCS Ninja exam. Thus if drawing diagrams help me expedite solving such problems, I knew I had to master the art of this practice. This type of problem can become more complex if the number of cities is increased. The problem can also become complex if some of the rules are not straight lines and are circular or elliptical in shape connecting the different cities.

## Arithmetic Digit Problems

The problems on the number system can be of various types in the TCS Ninja exam. For example, a person might choose a particular number, and then mentions that the number exceeds the sum of its digits by a specific value. The problem might further state that if the numbers increased by a particular value, the result is the same as a number formed by reversing the digits. The problem can be made more complex if equations formed are mentioned using multiplication and division. Such a type of problem requires being able to easily form equations and resolve the variables quickly. Based on the number of equations, the number, amount of time taken can also increase proportionately in such types of questions. I wanted to make sure that such types of number system problems did not scare me. I made sure I practiced a lot with numbers having three or four digits. Being able to handle such larger numbers gave me the confidence that I will be able to solve 2 to 3 digit problems easily. Some of the problems I intentionally wanted to make more complex by adding my own multiplication and division logics. With such complex relations between the digits of the number, I took more time to solve the questions. But it also helped me increase my efficiency in handling such types of equations. This type of question might seem simple, but often there are hidden logics embedded in them. Usually this type of question does not include fractions as that would make it more complex, but I practiced nevertheless.

## Arithmetic and Algebra

A type of problem from algebra can be related to perfect square numbers. We may be provided with a number series along with a variable inside that. Now the question might ask for what value of that variable will the summation of the series be a perfect square number? In such types of problems, it is often helpful to replace the variable with a value and test. Also, if we can form the equation in terms of the square of the sum of two variables which we are familiar with, we can replace one of the variables as per the equation given and then find the unknown variable. Being familiar with the square and cube of the sum of different variables is thus very crucial for the TCS Ninja exam. Sometimes we may be required to form the equations with the given logics using square roots or cube roots as well. Such types of cases might become more complex and take more time to solve. However, with the appropriate forming of the equations, it is possible to find the answer of the variables in the given amount of time in the main exam. Extensive practice of such types of equations where we have to find the value of the variable is important. I wanted to make sure I am able to solve all such types of problems related to equations and unknown variables in them.

## Fraction Problems

Questions on fractions are also important in the TCS Ninja exam. For example, there might be a question regarding a bag full of balls of different colors. A fraction of the balls in the bag are blue. And the rest are yellow in color. Now the question might mention that if a particular fraction of the blue balls and a particular fraction of the yellow balls are defective, we have to find the total number of balls if the number of balls that are not defective is given. In such a scenario, we have to form an equation and equate it with the number of balls that are not defective. This is because the number of balls that are not defective is given to us. Logically, following the logics with the given information step by step will allow us to form the equation. The problem can be made more complex with more balls of different colors. Or it can also be made more complex with more fractions that are not exactly divisible with each other and may content prime numbers. I wanted to make sure that I am able to score complete marks in any such type of problem in the TCS Ninja exam. For this reason, I made sure I practiced hard and even sometimes I created my own complex problems so that I did not have any surprises waiting for me during the exam. The question might also sometimes involve more than one variable in which one of the variables might get cancelled out at the end.

## Permutation and Combination

Permutation and combination is an important topic for the TCS Ninja exam. For example, the question might mention that a few given digits can form 4 digit numbers. Repetition of the digits is also allowed. Now the question asks us to find the sum of all the possible digits that can be formed using these given digits. Such types of problems of permutation and combination can be solved by implementing the formulas which we have learnt in these chapters. Since repetition of the digits is also allowed, we have to be careful so as not to miss out any such combination that can be formed. It is important to be able to solve such types of problems when numbers are repeated and also problems when numbers are not repeated. Based on the given situation, we will have to adjust our formulas and calculations accordingly. In certain cases, if a number begins with zero, we might have to adjust our calculations. Being thoroughly competent in permutation and combination type problems became a priority for me. I wanted to make sure that I was able to solve such types of problems even when special scenarios were presented. I often struggled remembering the formulas to implement and when to use which formula. I made sure I practiced a lot so that I am able to recall most of these formulas under stressful situations. Out of practice helped me a lot to gain confidence in permutation and combination type of problems.

## Word Letters Arrangements

A specific type of problem in permutation and combination can be related to rearranging the letters of a particular word. For example, we might be presented with a word and the question might ask us how many words can be formed using the letters of this word so that all the vowels in the given word are always together. To solve such a type of a problem, we have to form two groups of letters, one group will be for vowels and the other group for consonants. We will have to find in how many ways the vowels can be arranged among themselves. Then considering the vowels as one group, we will have to find in how many ways a word can be formed. It is important to remember that we do not miss out any vowel while calculating. Solving such a type of a problem will require us to apply the presence of mind as well as all the formulas that we have learnt in the chapters of permutation and combination. I wanted to make sure that I am able to solve large words with multiple vowels. I do not want to miss out the opportunity and I also wanted to solve the problems of this type at a fast pace during the TCS Ninja exam. Instead of a particular word, the question might also present us with a combination of words, often forming a sentence. Such types of problems will require us to form more calculations and involve longer time.

## Mensuration Interview Questions

Questions on mensuration are always important in the TCS Ninja exam. For example, the question might provide the dimensions of a particular room and the dimensions of a brick. Now the question might ask us how many bricks will be required to build a particular room. The question can be made more complex by multiplying the number of rooms and modifying their dimensions. Thus we will have to calculate the number of bricks required to build each room, where each of the rooms are of different dimensions. I loved geometry and mensuration problems. So I wanted to make sure that I did not struggle in any such type of problem in a subject that I loved. Instead of a simple shape, the problem can be made more complex if the rooms are of different shapes. In such cases, we have to apply the different formulas for each of the shapes to calculate the answer. Hence it is extremely critical to remember the formulas of the different shapes. Making notes and revising them repeatedly often helps to recall this type of formulas under the examination scenario. I made a note of all the important formulas of mensuration, an geometry and revised them repeatedly. A lot of practice and revising the formulas helped me to recall most of the complex logics during the exam. I realized that there is no substitute for hard work and a lot of practice. Talent can only take us thus far. The rest is for us to work hard to succeed in this exam.
