Questions about computer programming, data structures, algorithms, and system architecture may be asked during the interview.

Technical HR: Those who do well on the online assessment may move on to a technical interview, where they will be challenged to demonstrate their abilities by addressing specific technical challenges relating to the position. The interview could take place over the phone or in person. You may be invited for a more technical HR interview based on how well you do in the preliminary interviews. You could skip this one if you did particularly well in the previous round. The questions in this section will center on

  • Data Structures
  • Database Concepts
  • Approach to the given Scenario
  • Some logical puzzles

General HR: If a candidate acquitted themselves well in the technical interview, they may be invited to an HR interview, where they will be assessed in areas like communication, teamwork, and problem-solving. You've successfully reached the business if you've read this far. Questions during the Regular HR Interview will be more conversational in tone and may include things like

  • Your hobbies
  • Your family background
  • The reason you chose Zoho
  • Your location preference

Hired: At the end of the interview process, Zoho will determine which candidates performed the best and extend an offer to the ones who best meet their needs. Zoho may extend a job offer to you if you do well on both the written exam and the interview. The offer could include details regarding the position, salary, and benefits.

3) What is a hashing function?

A hashing function is a function that takes an input (a key) and produces a fixed-size output (a hash). It is commonly used to index and retrieve database or hash table items.

4) How do you design a program using Java?

The process of creating an application in Java is lengthy. Get started with coding by establishing a class that represents your program. The next stage involves creating the main method that will be used when the application is being executed. The final action is to run the program after it has been compiled.

Here's a list of everything you need to do:

  • Make a class that tells people what the program does.
  • Write the main method of the program. This method will run the program.
  • Make the program work.
  • Activate the program

5) What is normalization in the design of a database?

The process of normalization involves structuring a database to cut down on redundant information and strengthen the data's integrity. The task entails dividing enormous tables into several smaller, more manageable tables and determining the linkages that exist between each pair of tables.

6) What is the difference between stack and queue data structures?

The data structures of stack and queue are both considered to be linear. The primary distinction between a stack and a queue is that a stack follows the Last-In-First-Out (LIFO) principle, while a queue follows the First-In-First-Out (FIFO) principle.

[Releted Article - data structure interview questions and answers ]

7) How is a stack implemented?

Arrays and linked lists are the two most prevalent stack implementations.

If you employ an array, you must maintain track of the element at the top of the stack. The primary element is the one that will be removed first from the stack. To push an item into the stack, append it to the end of the array. To remove an element from the stack, delete it from the array's end.

If you employ a linked list, you must keep track of the list's head and tail. The head will be the first element to be removed from the stack. To put an item onto the stack, place it at the beginning of the list.

8) What are the advantages of version control systems such as Git?

Git and other version control systems have several uses in software development projects, such as 

  • Change tracking 
  • Business continuity.
  • Team collaboration
  • Rollback functionality, and 
  • Code backup for disaster recovery 

9) What kinds of joins are there in SQL?

When working with SQL, you can do four different types of joins: 

  • INNER JOIN
  • LEFT JOIN
  • RIGHT JOIN, and 
  • FULL OUTER JOIN.

10) What is the difference between JRE, JDK, and JVM?

  • A set of programs known collectively as the Java Runtime Environment (JRE) is needed to activate Java software.
  • The Java Virtual Machine (JVM) is a bytecode execution environment also known as the Java Runtime.
  • The Java Development Kit, or JDK, is a tool for creating applications. Java Runtime Environment (JRE) is a collection of programs required to run Java applications.

11) When is serialization used?

Serialization in Java lets us turn an Object into a stream that we can then send over the network, save as a file, or store in a database for later use. Its main job is to remember how something is so that it can be made again if needed.

12) Find which subsequence is the longest increasing subsequence in the given array i.e, [3, 4, -1, 0, 6, 2, 3].

The sub-sequences are groups of sequential, progressively more valuable array elements. For instance, the largest ascending subsequence in the array [3, 4, -1, 0, 6, 2, 3] is [-1, 0, 2, 3].

13) In a database, are NULL values similar to those of zero or empty space?

No, Unlike the values zero and a blank space, a NULL value indicates that the corresponding information is either unavailable, unknown, already assigned, or irrelevant. In contrast, an empty space represents a character, and a zero value represents a number. This means that a NULL value is not the same as a value of zero or a blank space because a NULL value represents. 

14) What is the difference between a pointer and a reference?

The difference between a pointer and a reference is that the former is a variable that stores the memory address of another variable. At the same time, the latter is an alias or another name for a variable.

15) What is the difference between call by reference and call by value?

When a function is called by reference, it receives a pointer or reference to the actual variable. On the other hand, when a function is called by value, it receives a copy of the value stored in the variable.

16) What is a virtual function in C++?

Polymorphism is made possible by a base class's virtual function, which a derived class can replace with its own version of the method by declaring it in its own class. At runtime, the behavior of the function is figured out. This makes it possible for the function to have dynamic behavior that changes depending on the instance of the class.

17) What is a constructor in C++?

Constructors are special class member functions responsible for initializing the objects the class creates. It shares the same name as the class, but the type of return value is not specified.

18) What is the difference between a function and a method in OOP?

An object's or a class's method is a function bound to that object or class, while a function is a self-contained piece of code that receives input and returns output. In computer programming, you'll find both types of code snippets.

19) What do you mean by recursion?

Recursion is a term that is used in computer programming to describe the process of a function calling itself. It is typically used to find answers to problems that may be broken down into a number of distinct but related subproblems. This type of problem is amenable to partitioning.

20) Explain briefly about the database index.

A data structure known as a database index makes it possible to search and retrieve information from a database more expediently. This is made possible by the database index. This is achieved by creating a copy of the sorted version of certain of the columns in the database table.

Zoho Technical Interview Questions for Experienced

21) When can super keywords be used?

Here are some ways that you could use this super keyword:

  • Accessing data from a parent class is made more difficult when a subclass also utilizes the names of its members.
  • Within the child class, call the parent's Object() function (which may take parameters) using [native code].
  • This is because the methods of the parent class have been overridden by the child classes, and it is required to get the original implementations.

22) What is the meaning of "Sockets in OS"?

In operating systems, the socket serves as a terminal for communicating between processes, or IPC. In this context, an IP address and port number are taken as synonymous with the endpoint. With sockets, developers can speed up the process of creating programs with network communication capabilities. It also lets two different processes running on the same machine or on different machines talk to each other and share information. Its main use is in computer systems that use the client-server model.

23) What is a software bug?

An unexpected issue with hardware or software is called a bug. A software bug is a flaw in the code that leads to incorrect or unexpected behavior by the program or its output. The most common cause of software failure is interference from factors the programmer didn't anticipate. Problems caused by minor flaws, such as unresponsive screens or illogical error messages, typically have no bearing on the program's functionality.

24) What is the difference between a stack overflow and a heap overflow?

A heap overflow happens when the memory allocated to the heap is used up, whereas a stack overflow happens when the memory allocated to the stack is used up. Both can result in the software crashing or behaving suddenly.

25) What is a deadlock in operating systems?

A deadlock is when two or more processes can't move forward because they are waiting for each other to release resources. This leads to a standstill. 

26) What is the difference between a switch statement and an if-else statement in programming?

A switch statement can be used to decide which of numerous blocks of code to execute based on a condition, while an if-else statement can only decide between two possible outcomes. 

27) What measures can be taken to guarantee the security of data in a web application?

To guarantee the security of data in a web application, various steps can be taken, such as

  • Encryption,
  • Input validation,
  • Logging, and Monitoring,
  • Regular Updates and Patching,
  • Secure Development Practices.

28) Differentiate between the "throws" and "throw" keywords in Java?

Below is a comparison between the "throw" and "throws" keywords in Java:

Keyword

Purpose

Usage

throw

Employed to throw an exception explicitly.

throw new Exception("Error message");

throws

Utilized to specify exceptions that a method may throw.

public void method() throws Exception {...}

29) Explain briefly about Python decorators.

In Python, a decorator is a function that can augment the functionality of another function or class by taking it as performing some modifications and returning the updated class or function. This approach enables developers to enhance the behavior of a function or class without altering its source code.

30) Can you define "design pattern" and give some examples of patterns you've used?

In the field of software design, a "design pattern" refers to a generic and reusable solution to an issue that crops up frequently. The Singleton, Factory, Observer, and Decorator design patterns are all examples of common design patterns.

31) What is a code review, and what are some best practices for conducting a code review?

In a code review, multiple programmers examine and critique the work of a single programmer. Code reviews benefit from having well-defined goals, receiving and acting on constructive criticism, and using a checklist.

32) What is a database index, and how does it improve performance?

A database index is a type of data structure that makes getting data from a table faster. It makes it easy for the database to find rows that meet a certain condition and reduces the number of disk I/O operations.

33) What is a thread pool, and how does it work?

A thread pool is a collection of threads that can perform multiple tasks concurrently. It can improve performance by making it easier for each task to start and stop its own thread. A thread pool is a type of software design pattern used in computer programming to make programs run simultaneously. It is also sometimes called a replicated worker or worker-crew model. 

34) What do you mean by message queue?

Async communication between processes is made possible through message queues, which are data structures. Message queues are lightweight buffers for storing messages temporarily and endpoints for connecting software components to the queue for sending and receiving messages. The purpose of these messages can range from a direct request to a thorough breakdown of a problem. Buffering messages and decoupling the sender and receiver can improve throughput, especially in highly congested environments.

35) What is a load balancer, and how does it work?

A load balancer can either be a piece of hardware or a piece of software. It aims to improve performance, stability, and scalability by distributing network traffic over numerous servers. The load can be distributed in various ways, using methods like round-robin, least connections, and IP hash.

36) Write a program to calculate the sum of primes present as digits of a given number N.

Input: 333
Output: 9
Explanation: 3 is a prime number. It is present 3 times. So 3+3+3 = 9.
#include <iostream>
using namespace std;
bool isprime(int n){
   if(n<=1)
   return false;
   for(int i=2;i*i<=n;i++){
      if(n%i==0)
        return false;
  }
  return true;
 }
    int primeSum(int N){
       // code here
       int n=N;
       int res=0;
       int sum=0;
       while(n)
       {
          int rem=n%10;
          if(isprime(rem)){
          sum+=rem;
          }
          res=res*10+rem;
          n/=10;
        }
        return sum;
      }
int main() {
   // your code goes here
   int n;
   cin>>n;
   cout<<primeSum(n);
   return 0;
}

37) Reverse and add a number until it forms a palindrome or exceeds 5 repetitions.

Input: n = 23
Output: 55
Explanation: reverse(23) = 32, then 32+23= 55, which is a palindrome.
#include <iostream>
using namespace std;
long long rev(long long n){
   int sum=0;
   while(n>0){
      int rem=n%10;
      sum = sum*10 + rem;
      n/=10;
   }
 return sum;
}
   long long isSumPalindrome(long long n){
      // code here
      int sum;
      sum=n;
      for(int i=0;i<6;i++){
         if(sum==rev(sum))
         return sum;
         else
         sum+=rev(sum);
      }
      return -1;
   }
int main() {
   // your code goes here
   long long n;
   cin>>n;
   cout<<isSumPalindrome(n);
   return 0;
   }

38) How to reverse a string in C?

We will use the strrev() function to reverse the string.

#include <stdio.h>
#include <string.h>
int main()
{
//declare the size of the string
char str[100]; 
printf(\n “Enter the String: ”);
scanf(“%s”, str);
//declare strrev() function
printf(\n Output: %s”, strrev(str));
return 0;
}

39) Write a program to get the output:

E.g. 1: input: a1b10

Output abbbbbbbbb

Eg. 2 input b3c6d15

output bbbccccccddddddddddddddd

The number varies from 1 to 99.

#include<stdio.h>
#include<string.h>
int main()
{
   int n,i,j,count=0;
   char a[50],ch;
   scanf("%s",a);  
   for(i=0;i<strlen(a);i++)
   {
       if(a[i]>='0'&&a[i]<='9')
       {
           count=(count*10)+(a[i]-'0');
       }
       else if(count>0)
       { count--;
           for(j=0;j<count;j++)
           {
                printf("%c",ch);
           }count=0;
       }       
       if(a[i]>'9')
       {
           ch=a[i];printf("%c",a[i]);
       }
    // printf("%d\n",i);
       if(i==(strlen(a)-1))
       {--count;
           for(j=0;j<count;j++
           {
               printf("%c",ch);
           }
       }
   }
   return 0;   
}

40) Find the longest palindromic substring in a string?

string getLongestPalindrome(string s) {
   int n = s.size();
   int index = 0, palindromeLength = 1;
   for (int i = 1; i < n; i++) {
       int left = i - 1, right = i;
       while(left >= 0 && right < n && s[left] == s[right]) {
           if(right - left + 1 > palindromeLength) {
               index = left;
               palindromeLength = right - left + 1;
           }
           left--;
           right++;
       }
      left = i - 1;
       right = i + 1;
       while(left >= 0 && right < n && s[left] == s[right]) {
           if(right - left + 1 > palindromeLength) {
               index = left;
               palindromeLength = right - left + 1;
           }
           left--;
           right++;
       }
   }
   string ans = "";
   for (int i = index; i < index + palindromeLength; i++) {
       ans += s[i];
   }
   return ans;
}
