Zoho Corporation Interview Questions and Answers
With more than 60 million users, more than 1000 extensions, and more than 40 products, Zoho Corporations is a software as a service (SAAS) firm that is expanding rapidly. Here are the frequently asked Zoho Corporation interview questions and answers to help you prepare for the upcoming interviews.
Zoho Corporation Interview Process
Five rounds of written exams, basic and advanced programming, and HR rounds (technical and general) typically comprise ZOHO’s interview procedure.
Written Test: It is an aptitude exam that freshers must take. There are two sections to the test.
- Test your general aptitude (time, work, profit and loss, percentage, ratio) to see how well you can solve problems.
- Test your fundamental C programming knowledge with C-Programming Aptitude (Nested Loops, Recursions, Flow Charts, and Pointers).
Basic Programming: Java, C, and C++ will be the foundation of the questions. There will be five programming questions covering sorting algorithms, loops, recursions, pattern printing, and array manipulations.
Advanced Programming: This round will assess your proficiency with data structures, algorithms, and problem-solving techniques. Depending on your experience, you must develop or create systems, games, or apps using either C, C++, or Java programming.
Technical HR Round: This round, which includes basic data structure questions, guessing questions, riddles, etc., usually ends in 30 to 40 minutes.
General HR Round: This is the easiest stage because HR just needs to know why you want to work at Zoho, and how much you hope to be paid.
Zoho Interview Questions and Answers for Freshers – Technical
1. What are the OOPs concepts?
The programming language that makes use of objects is known as OOPs, or object-oriented programming. It is employed in the design of applications that use objects and classes. It offers ideas like encapsulation, polymorphism, inheritance, abstraction, etc.
2. What is data structure?
The data in a system can be seen, processed, arranged, and altered using data structures. The relationship between data items is displayed, and efficiency, reusability, and abstraction are all improved.
3. Combine two sorted arrays so that their elements don’t repeat.
Example: Input:
Array 1: 2,4,5,6,7,9,10,13
Array 2: 2,3,4,5,6,7,8,9,11,15
Output:
Merged array: 2,3,4,5,6,7,8,9,10,11,13,15
4. What is the Bubble Sort Algorithm?
One of the simplest sorting algorithms is bubble sort, which compares neighboring elements and swaps them if they are bigger or smaller depending on the stated conditions. Essentially, each element in the array is compared with every other element until the last element is located.
5. Explain the operation of Python’s garbage collection system.
Python makes use of both a cyclic garbage collector and reference counting. Each object has a reference count that changes depending on whether new or removed references are made to it. The memory is recovered instantly when the reference count reaches zero. Python utilizes a cyclic garbage collector to identify cycles and clean them up regularly.
6. Describe the Python Global Interpreter Lock (GIL). What effect does it have on multi-threaded applications, and how may its restrictions be overcome?
To prevent several native threads from processing Python bytecodes concurrently within a single process, the GIL is a mutex that safeguards access to Python objects.
Because of the non-thread-safe memory management in Python, this lock is required. The GIL affects how well multi-threaded and CPU-bound Python scripts run.
7. How do TCP and UDP vary from one another?
The error-checking, flow-controlling, connection-oriented Transmission Control Protocol (TCP) guarantees continuous data delivery. UDP doesn’t have a problem with disconnections, but it can’t guarantee delivery because it doesn’t have error checking.
8. In C, how can a string be reversed?
To reverse the string, we’ll utilize the strrev() method.
#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);
printf(\n Output: %s”, strrev(str));
return 0;
}
9. Explain a database index?
One kind of data structure that speeds up data retrieval from a table is a database index. It minimizes the number of disk I/O operations and facilitates the database’s ability to locate records that satisfy a given criterion.
10. How does the volatile keyword work in Java?
In Java, the volatile keyword makes sure that a variable is read from and written to main memory instead of being cached in the local memory of a thread. While visibility is guaranteed, atomicity is not.
It makes sure that any write to a volatile variable creates a happens-before relationship, making the writing visible to all subsequent reads by other threads. It is utilized when many threads access a variable.

11. What distinguishes an interface in Java from an abstract class?
Abstraction class: If a class is non-creatable and has methods that can be both non-abstract and abstract at the same time, it is considered abstract.
Interface class: Any class can implement an interface, which is a set of abstract methods and constant variables. An API (application programming interface) is another name for an interface.
12. What does the phrase “Sockets in OS” mean?
Operating systems use the socket as a terminal for interprocess communication, or IPC. An IP address and port number are regarded as equivalent to the endpoint in this situation. Developers can write programs with network communication capabilities more quickly by using sockets.
Additionally, it enables information sharing and communication between two distinct processes that are executing on the same machine or on separate machines. It is mostly utilized in client-server computer systems.
13. What is a bug in software?
A bug is an unforeseen problem with software or hardware. A software bug is an error in the code that causes the program or its output to behave incorrectly or unexpectedly.
Interference from unanticipated circumstances is the most frequent reason for software failure.
Minor bugs that result in non-functional screens or nonsensical error messages usually don’t affect the program’s operation.
14. What is the function of a thread pool?
A group of threads that are capable of handling several jobs at once is called a thread pool. By facilitating the start and termination of each job on its own thread, it can enhance performance.
Programmers can execute multiple applications simultaneously by using a form of software design pattern called a thread pool. It is also known as a worker-crew model or duplicated worker.
15. Create a program that adds up all of the prime numbers that make up a given number N.
#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;
}
16. What is a code review and what are some recommended methods for carrying out one?
Several programmers look at and comment on the work of one coder in a code review. The use of a checklist, receiving and acting upon constructive criticism, and having clearly stated goals all contribute to the success of code reviews.
17. How do you use Java to design a program?
Making an application in Java is a time-consuming task. To begin coding, create a class that serves as the representation of your program. Developing the primary method that will be utilized when the application is run is the next step. Running the program after it has been compiled is the last step.
This is an outline of all the things you must do:
- Create a class that explains the functions of the application.
- Write the program’s primary method. The software will run this way.
- Ensure that the program functions.
- Turn the program on.
18. Create a program in C to find a duplicate in array.
#include <stdio.h>
int main()
{
int arr[] = {10, 20, 25, 30, 35, 30, 20, 10}
int size = sizeof(arr)/sizeof(arr[0]);
printf(\n “Duplicate Elements:”);
for(int i = 0; i < size ; i++
{for int j = i + 1; j < size; j++)
{if(arr[i] == arr[j]
printf(“%d\n”, arr[j]);
}
}
return 0;
}
19. In a string, find the longest palindrome substring.
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;}
20. How does a load balancer operate and what does it do?
A load balancer may consist of either software or physical components. The goal is to increase scalability, stability, and performance by spreading network traffic over multiple servers. There are other strategies to disperse the load, including IP hash, least connections, and round-robin.
