TCS Digital Hiring Process 2022

TCS Digital Previous Questions Questions and Mock Test

TCS has released a set of sample questions that would help you predict the TCS digital pattern better. Here are a few sample questions from each of the above-mentioned sections.

Question 1

The words Ocean and Cube can be related through a set of words/phrases in a specific order (path) as below:

Ocean, Water, Ice, Ice cube, Cube

In a similar way, relate Alert and Timeline.

• The score increases if you can relate them in more than one way.
• A shorter path gets a higher score than a longer path.
• Use a new-line between paths. Use a comma between phrases in a path.

Possible solution: Alert, Facebook, timeline

Question 2

The following note gives one part of a position paper on the future of Life Science. Please read the passage, and identify which of the indicated technologies would be useful for these trends strictly based on the passage. Note that more than one technology may be applicable.

Passage:

Life sciences companies are focusing on keeping patients digitally informed with accurate medical information on diseases, related drugs, and devices through microsites, mobile apps, and informative videos. Rather than replacing healthcare providers (HCPs), the digital medium will complement the quality of healthcare available for patients. Platforms or patient healthcare portals such as ChARM PHR help users manage not just their personal health records and medication history but also care plans, immunization records, health and wellness tips, and so on. patients like me and other such patient networking portals connect people with similar medical conditions and help them better understand medication regime, side effects, and cost impact, among others.

In such patient networks, some members are key influencers or ‘digital opinion leaders’. Life sciences companies can collaborate with these community leaders to share their opinions and information related to new therapies, trials, and care methods with others. Social networking sites can also provide information on specific campaigns to access drug vouchers, coupons, health-tips, and so on. Companies are leveraging social media channels by creating community pages for disease condition information well within the required compliance and regulation. Unimetric’s report on pharma-social-media-trends states that most of the pharmaceutical companies are active on five out of six social networks with the majority preferring Twitter, LinkedIn, Facebook and YouTube.

MerckEngage is one such communication channel available across social media. Digital technologies are now being leveraged to reduce medication non-adherence too with mobile-based trackers and schedulers, sensor-based devices such as inhalers, smart pillbox, and smart pills. Sensor-enabled medical devices such as oximeter and blood glucose monitors are capturing vital health stats for patients using their smartphones. These are transmitted to physicians and care teams, who provide patient-specific recommendations.

Possible Technologies:

IOT, connected cars, Nudging, social media, distributed databases, non-relational databases, visualization, chatbots, semantic nets, Deep Learning, neural networks, speech technologies, behavioral analytics, cloud computing, Hadoop, mobile technologies, gesture detection, collaborative technologies, knowledge engineering, speech technologies, language translation, simulation.

Question-3

In a singly linked list, each node has a pointer to the next node in the list. The last node points to nothing. Eesha wrote an iterative function that takes the first node of a singly linked list as an argument, reverses the list, and returns the first node from the resulting list. However, she did not get the correct result. The pseudo code for this function is given below. In which line number has she made a mistake? (fill in the blank)

1. public Node reverse(Node x)
2. {
3. Node first = x;
4. Node reverse = x.next;
5. while (first != null)
6. {
7. Node second = first.next;
8. first.next = reverse;
9. reverse = first;
10. first = second;
11. }
12. return reverse;
13. }

Solution: In the above problem the 4th line should ideally be Node reverse = null;

Question 4:-

Please Choose one of the choices A, B, C or D.

Each of Alia, Betty, Carol, and Dalia took a test. Each of them answered at least one question correctly, and altogether they answered 67 questions correctly. Alia had more correct answers than anyone else. Betty and Carol together answered 43 questions correctly. How many correct answers did Dalia have?

A) 1 B) 2 C) 3 D) 5

Solution:

Total 67 Questions.

Given, Betty+Carol =43 Questions        [possible combinations = (1,42),..(20,23),(21,22),(22,21)….(42,1) ]

Alia+Dalia =24 Questions          [possible combinations = (1,23),(2,22),….(23,1) ]

given, at least 1 questions is solved by each & Alia solved maximum.

Alia solved maximum 23 questions only when Betty:Carol=21:22 or 22:21

so, Dalia solved 1 question.

Question 5

You need to write a program to accept input in the format specified, and produce output as specified. The program will be run against a number of test cases (2 public, given as examples, and the others private (which will not be known to you). The performance of the program (correctness of output and time taken to execute) against the test cases will be used to evaluate.

Max Square Sum: Given a square array of size N x N where each cell is filled with a number between -9 and 9. A sub-square of size k is any set of k contiguous columns and k contiguous rows. For any sub-square, the sum of elements in its cells is called a sub-square sum. Given the N x N square, write a program to find the maximum sub square sum.

Note that a 1 x 1 square (k=1) is not considered a sub square)

Input: N, giving the size of the square

The next N rows each contain N space-separated integers giving the values of the cells in the rows of the square, left to right.

Output: One integer, the maximum sub-square sum

Constraints

N <= 1000

Example 1 :

Input:

4

2 -8 4 -6
7 1 -5 3
-9 7 6 5
8 3 2 -4

Output:

20

Explanation:

The 2 by 2 square sums are 2 -8 -4 6 9 9 9 18 9 The 3 by 3 square sums are 5 7 20 18 And the 4 by 4 square sum is 16. Hence the maximum sub square sum is 20.

– TCS has mentioned that it is looking for candidates who don’t just clear a written test but
also have an idea about the latest digital technologies. So, at least do a basic Google research on technologies like IoT, Machine Learning etc; We have seen these questions in the Agility section of the paper.

While attempting the exam:

1. An answer to a question gets saved only if you press the “Save and Next” option on the screen. You can change the option later, by clicking on any other option or click on “clear response” if they want to leave the question unattempted.
2. TCS so far had negative marking in all its exams. However, there was no mention of the negative marking in the instructions of the TCS digital Mock exam this time. So, there will be no Negative marking this time in TCS Digital 2021-22
3. You cannot switch between the sections. Once you submit the section, you cannot return back to it. All sections appear in the order shown in the above image explaining the TCS digital expected pattern.
4. Time from one section cannot be transferred to other section, so use the entire time to answer as many questions as possible or review the answered questions.
5. During the mock test given by TCS, there were 2-3 incomplete questions. Now, we are not sure if this is intentional or not. So beware when answering such questions. Do not assume anything and leave the question unanswered if they feel the question is incomplete.

Actual Exam Questions of 20th July –

Ques. 1Relate Factory and Forest.

Ques. 2 ‘NIGTH,WRIST,TIME’ the fourth word is WATCH. Then what is the fourth word for ‘MEASURE,WORM,VIDEO’.

Group the following 16 pictures into 3 categories of 4 pictures each. The purpose of the remaining 4 pictures is to mislead you.

List of items – 

Now our basic aim is to categorise into 3 categories for 4 each –

Note – These are 16 pictures, we have to catergorize in any order, its not like we have to pick 1 from each row. We can even find a relationship that has 4 picture in 1 singular row itself.

Now a lot of you may think first as politician as first category –

Category 1

1. Mahatma Gandhi
2. John F kennedy
3. Indira Gandhi
4. Jawahar Lal Nehru
5. Abraham Lincoln
6. Donald Trump

These are politicians

. But, they asked us to do 4 but these are six.

So let’s try again

Dead politician

as category will remove donald trump as he is alive.

But now again its 5 people we want 4

Dead Male Politician

Are Mahatma Gandhi, John F Kennedy, Jawahar Lal Nehru and Abrahan Lincoln.

Category 2

Some of you may think in terms of horoscopes also that image in row1 and column 3 is a horoscope and row 3 column 2 and row 4 column 2 is also. But, with horoscopes we cant make it 4. So let’s try something else –

Horns

The following 4 have horns –

1. Image Row 1 Column 3
2. Image R2C3
3. Image R4C2
4. Image R4C4

Category 3

One category is abstract which is basically something that is random and doesnt make sense R1C2, R1C4, R3C1and R3C1.

Category 4

One Category is Animals but there are 5 animals.

Lets exclude fish then there are 4 mammals.

Category 5

Black and white –

R2C1, R2C4, R3C3, R3C4.

Comment down at the end of the page and help others if you can make new categories of 4. We help you, you help us.

In this section TCS basically wants to recruit people who have high deductive logic which is a great skill in artificial intelligence and since one of the profile that they are offering is AI in TCS Digital this is crucial.

We will walk through the Reading Comprehension and find the Solutions with you. Those technologies are marked in Green in bracket as soon as we see them. We also suggest you to write on a paper the technology that you notice while reading the RC simultaneously.

Your Reading comprehension in the paper will also be about the business of a client which maybe a company like Tesla, Mercedes, Nestle, or govt organisation like Finance ministry, sports ministry, BCCI, FIFA etc or maybe a business problem like this one below –

Question 1

Life sciences companies are focusing on keeping patients digitally informed with accurate medical information on diseases, related drugs, and devices through microsites (web development), mobile apps (Android, iOS, Swift, Java), and informative videos(Social Media, YouTube). Rather than replacing healthcare providers (HCPs), the digital medium will complement the quality of healthcare available for patients. Platforms or patient healthcare portals such as ChARM PHR help users manage not just their personal health records and medication history but also care plans, immunization records, health and wellness tips, and so on (Database, DBMS, Hadoop, distributed databases, non-relational databases, visualization). patients like me and other such patient networking portals connect people with similar medical conditions(semantic nets, Deep Learning, neural networks, behavioral analytics) and help them better understand medication regime, side effects, and cost impact, among others.

In such patient networks, some members are key influencers or ‘digital opinion leaders’. Life sciences companies can collaborate with these community leaders to share their opinions and information related to new therapies, trials, and care methods with others. Social networking sites can also provide information on specific campaigns to access drug vouchers(Digital Marketing), coupons, health-tips, and so on. Companies are leveraging social media channels by creating community pages for disease condition information well within the required compliance and regulation. Unimetric’s report on pharma-social-media-trends states that most of the pharmaceutical companies are active on five out of six social networks with the majority preferring Twitter, LinkedIn, Facebook and YouTube. MerckEngage is one such communication channel available across social media.

Digital technologies are now being leveraged to reduce medication non-adherence too with mobile-based trackers and schedulers, sensor-based devices such as inhalers, smart pillbox, and smart pills. Sensor-enabled medical devices such as oximeter and blood glucose monitor are capturing vital health stats for patients using their smartphones(IOT, Nudging). These are transmitted to physicians and care teams, who provide patient-specific recommendations.

We have found some new answers and some common answers that TCS also gave in Sample Test.

Now the answers given by TCS are the follows –

IOT, connected cars, Nudging, social media, distributed databases, non-relational databases, visualization, chatbots, semantic nets, Deep Learning, neural networks, speech technologies, behavioral analytics, cloud computing, Hadoop, mobile technologies, gesture detection, collaborative technologies, knowledge engineering, speech technologies, language translation, simulation.

Outcome – We did see IOT hadoop etc. But, we strongly believe that connected cars is nowhere releated to the above Reading Comprehension.

But, yes we do found some decent things.

1. They talked about programming languages like Hadoop, DBMS
2. They talked about new data mining technologies like behavorial analytics
3. They talked about AI Technologies like – semantic nets, Deep Learning, neural networks, speech technologies
4. They talked about Artificial Intelligence

If you think that they will need a website or mobile app then the client or problem they are talking about in the reading comprehension will definitely have Database technologies like – Hadoop, DBMS, RDBMS, Database, SQL, NoSQL, Oracle, Cloud Computing (To store Data).

If they need website then definitely they need – Web development, HTML, CSS, mentioned new techs like Angular JS, ReactJS etc

If they(business) need customer support then to reduce client cost on hiring people they can have chat bots, speech technologies, language translation

If they need smart data analytics then you should include knowledge connection, neural networks etc.

Basically TCS Digital is hiring people to work on – Data mining, Data Analytics, Artificial Intelligence, Machine Learning, Devops, Chat bots etc.

So mention technologies that you think have emerged in last 10 years in IT.

Few more example would be IOT, Self driving, Car pooling, Image recognition, automation, robotics, Electric cars etc.

Type 2

Computer vision is a branch of computer science aims to enable computers to recognise and process images in a way that human vision does. It is similar to imparting intelligence and instincts that humans possess into a computer. Computer vision is closely related to artificial intelligence, as the computer must interpret and discern what it sees, perform the required analysis and provide insights for decision making; e.g., computer vision for driverless cars perform functions such object detection (road, traffic lights, pedestrians etc.), motion & speed detection, path prediction. Obviously this needs to be done real time and across all the entities in the ecosystem, so there is a huge amount of data to process in a very short time.

Deep learning is a popular set of methods used to achieve this. Scientists collect sizeable sets of data and use it in part to train the computer vision algorithm and in part to test the algorithm. Subsequently they build the ‘decision-making’ capability based on the algorithm’s outputs, e.g., intelligence added to stop the car once a pedestrian is detected crossing the road in front.

As a computer vision expert, you have recently attended the World Ophthalmic Federation summit, where a proposal has been tabled to develop ‘Nethra’- computer vision-enabled goggles for visually impaired. The federation has collected a dataset of 1,000,000 images taken from various head-mounted cameras simulating the typical paths of visually impaired pedestrians in New York City. Some images have multiple objects in front, other images do not, some are.

Arrange the items below in order of what you would do to build the solution:

1. Scale the object localization to support multiple objects
2. Validate the accuracy of the model using the test data
3. Build an image classifier that detects different types of objects
4. Split the Data into a training and test set with ratio 70:30
5. Build an object localization mechanism

This one we leave to the students comment down your answer in the comment section below with explanations.

Also, we will tomorrow post Coding Dashboard for TCS digital also. Book mark PrepInsta we are the most visited Placement Preparation website in India.
