ZS Associates Technical Interview Questions for Non-IT Candidates

Question 1:- Who is the creator of the C programming language? When was the C programming language created?

Answer:-

Dennis Ritchie developed the C programming language at AT&T Bell Laboratories in 1972.

Question 2:- Why is C classified as a middle-level language?

Answer:-

  • A mid-level language bridges the gap between machine and high-level languages. One of these programming languages is C.  
  • It can be used in both system programming (such as operating systems) and application programming (like spreadsheets). 
  • Machine and human language are more closely related at the middle level. That is why it is referred to as “Middle-level language”.

Question 3:- What are the four different sorts of OOPs?

Answer:-

There are four different types of OOPs 

  • Inheritance
  • Encapsulation
  • Polymorphism
  • Data Abstraction

Question 4:- What is a relational database management system (RDBMS)?

RDBMS stands for Relational Database Management System, which stores data in the form of tables and allows users to retrieve it via common fields between tables.

Question 5:- In Python, what is the difference between a list and a tuple?

List

Tuple

Lists are editable, which means they may be changed.

Tuples are non-editable, immutable ways.

Compared to tuples, lists are slower.

Tuples are more efficient than lists.

More memory is used.

Uses up less RAM.

The data in Python lists are written in array brackets [ ].

Round brackets are used to represent data in Python tuples ()

Question 6:- What distinguishes Python from other programming languages?

Question 7:- What are the benefits of using a C++ programme?

Answer:-

The following are some of the most significant advantages of the C++ programming language:

  • Message passing is an object-to-object communication mechanism.
  • C++ is a highly portable programming language, which implies that software written in it can run on any platform.
  • The C++ function library is extensive.
  • Classes, objects, inheritance, polymorphism, and abstraction are all concepts in C++, an object-oriented programming language.
  • Data concealing assists programmers in creating secure applications that are not vulnerable to intruders.

Question 8:- Why do you think Java is platform-independent?

Answer:-

Because its byte codes can operate on any system, regardless of the underlying operating system, Java is known as platform-independent.

Question 9:- What exactly is a queue?

Answer:-

A queue is a type of data structure that can be used to simulate a list or stream of data. New elements are added to one end of the building, while current elements are removed from the other.

ZS Associates HR Interview Questions

Question 1:- Tell Me something Which You Haven’t Mentioned In Your Resume.

Answer:-

I’m pleased with my capacity to adjust to changing conditions, which I don’t include on my résumé. I’d gone to a camp where there were few options for staying and eating. It was difficult because of the extreme cold and my lack of gear, but I went on a hunt, found some rocks, and created a fire for myself and my coworkers, and we made it through the night. That way, I’m confident in my ability to adapt to any situation.

Question 3:- What are your strengths and weaknesses?

Answer:-

It can be difficult for me to describe my strengths and weaknesses because I am familiar with both notions. Self-motivation is a trait I possess. If it helps me grow and learn, I am willing to work hard and regularly to reach a goal. Even when faced with numerous impediments, I can motivate myself to complete a task. However, being overly motivated is a problem of mine since it causes me to forget myself and become very goal-oriented. If it’s a collaborative project, my personal aspirations become a burden for them, and I end up with conflicts and group breakdowns as a result. I’ve been working on this for a few months now, where I establish a boundary for myself and the team, trying not to let my ambitions and aspirations become a source of pressure for others.

As a result, both my strength and weakness stem from the same characteristic.

Question 4:- What is the difference between hard work and smart work?

Answer:-

In order to respond to this topic, I believe it is necessary to redefine the terms “smart work” and “hard labor” in today’s environment. While many of us consider hard effort to be a sort of “physical action”, smart work is considered a form of “mental capacity”. This was true before the Internet, but it no longer holds true. Success is all about doing smart work every day. This is difficult labor in and of itself. This field attracts a lot of attention. The goal is to provide clients with the finest possible service in a timely way. It takes a lot of time to keep producing outstanding work every day, but my agency has won the ‘Best Agency Award’ for the past few years, which indicates our commitment to excellence. I, too, bring something with me. As a result, I feel confident in my ability to work diligently.

Question 5:- What if we don't select you?

Answer:-

If I am not chosen despite performing well in the screening process, it is evident that your performance expectations from the applicant are higher. I’ll give it my all the next time, and in the meantime, I’ll work on improving my talents.

Question 2:- What is the definition of an operating system?

Answer:-

The operating system is a piece of software that allows computer hardware and software to connect and work together. It is the most crucial component of a computer system; without it, the computer would be nothing more than a box.

Question 3:- What is the process of quicksort?

Answer:-

Quick Sort is a regularly used sorting algorithm in computer science. A divide and conquer algorithm is Quicksort. It then recursively sorts the sub-arrays by creating two empty arrays to retain values less than the pivot value and elements larger than the pivot value. 

The algorithm consists of two basic operations: 

  • Swapping items in place 
  • Splitting a segment of the array. 

Quicksort employs a divide-and-conquer strategy. Using ‘pivot’ divides the list into smaller parts. The values that are less than the pivot are in the left partition, while the values that are bigger are in the right partition. Quicksort is used to recursively sort each partition.

Question 4:- What is bubble sort and how bubble sort works?

Answe:-

  • Bubble Sort is the most basic sorting algorithm, which works by exchanging neighboring components in the wrong order repeatedly. 
  • Bubble sort is a comparison-based algorithm that compares each pair of adjacent elements and swaps elements that are out of order. Because the temporal complexity is O(n2), it is not suitable for huge datasets.

Question 5:- State the properties of B Tree?

Answer:-

All of the attributes of a M way tree are contained in a B tree of order m. Additionally, it has the following features.

  • Each node in a B-Tree can have up to m children.
  • Every node in a B-Tree has at least m/2 children, with the exception of the root and leaf nodes.
  • At least two root nodes are required.
  • All leaf nodes must have the same level.

Question 6:- What do you mean by the assignment operator (=) and equal to (==)?

Answer:-

Equal to Operator (==): An equality relational operator that compares two expressions to check if they are equal, returning true if they are and false otherwise.

Assignment Operator (=): Assignment Operator is used to give a variable a value. As a result, we can evaluate a complex assignment operation within the equality relational operator.

Question 7:- What is the 3-Tier architecture?

Answer:-

Between the client and the server is another layer in the 3-tier design. The introduction of 3-tier architecture is for the benefit of users since it provides a graphical user interface (GUI), which makes the system more safe and accessible. In this architecture, the client-side application communicates with a server-side application, which then communicates with the database system.

Question 9:- What is Artificial Intelligence?

Answer:-

Artificial intelligence is a branch of computer science that focuses on creating intelligent machines or computer systems that can mimic human intelligence. Artificial intelligence-powered machines can function and behave like humans without the need for human involvement. Artificial Intelligence applications include speech recognition, customer service, recommendation engines, and natural language processing (NLP).

Question 10:- What are the benefits of Artificial Intelligence?

Answer:-

  • Efficiency has improved. 
  • Improved Workflows
  • Reduced Human Error Rates
  • Deeper Data Analysis
  • More Informed Decision Making
  • 24 / 7 Availability are just a few of the benefits of AI technologies.
