Mindtree Interview Questions for Freshers

1. What do you mean by Data Type in Computer Programming?

A data type is a value or form that a variable can have. You can perform mathematical, logical, and relational operations without errors based on the data type. Boolean, integer, character, string, floating point number, and void are a few examples of data types. The following data types and examples will help you to understand clearly.

Data Type	Form	Example
String	Alphanumeric characters	Bob, Alice, Hello
Character	Text is encoded in numerical form	97, which is equal to ‘a’
Integer	Whole numbers	2,44,88
Floating Point	Number with a decimal point	2.46,3.69
Boolean	Represents logical functions	TRUE, FALSE

2. What do you understand by Data Complexity?

Data complexity denotes the size as well as intricacies of data. It mainly depends on four parameters. They are the data structure, variety, data size, and abstraction.

Data Structure: It indicates the relationships between the data elements. As the number of connections increases, the data complexity also increases.

Variety: It represents the heterogeneity of data. As the data structure becomes more complex, the data complexity also increases.

Data Size: It represents the volume of data. As the volume of data increases, the data complexity also increases.

Abstraction: It is the process of hiding unnecessary information and representing only the necessary information. The abstracted data is usually more complex than the raw data

3. State the differences between Process and Thread

Process	Thread
Essentially, the process is a program scheduled for execution.	A thread is nothing but a set of instructions that can be a part of a process. In other words, a process can have many threads.
A process can have many states, such as new, ready, waiting, running, suspended, and terminated.	It has only three states such as ready, running, and blocked.
A process is a heavyweight element	A thread is a lightweight element
ending a process will take time.	We can quickly end a thread
We can isolate processes	We cannot separate threads

4. What do you mean by Foreign Key, Super Key, and Candidate Key in DBMS?

Foreign Key: A column or set of columns in a table associated with another table's primary key column.

Super Key: An attribute or set of features is used to identify table rows.

Candidate Key: It is the subset of the super key. It is an attribute or set of features used to identify tuples in a table.

5. What do you mean by BCNF?

BCNF refers to Boyce-Codd Normal Form. It is the fourth form of normalization in databases. It is essential that we need to perform all levels of normalizations for multidimensional database systems. As a result, you can remove redundant data from the databases and bring consistency. You can apply BCNF only when the following criteria are satisfied.

• BCNF must be in the 3NF level
• One of the reference tables must have a primary key.

6. What is the need for Memory Management?

We perform Memory management to utilize memory resources efficiently. Allocating suitable memory sources to multiple tasks is the most vital part of memory management. With memory management, we can efficiently perform multiprogramming. Not only that, we can eliminate fragmentation issues, track, and record memory resource usage, and significantly ensure data integrity

7. Explain Runtime Error

A runtime error is an error that arises while you are running a program. A bug is another name for a runtime error. It is essential that we need to identify bugs or runtime errors before releasing software. Logical errors and division by zero errors are a few examples of runtime errors.

8. Describe HTTP and HTTPS Protocols in Computer Networks.

HTTP is the short form of HyperText Transport Protocol. This protocol uses hyper-structured text and provides web browsers and servers with communication standards. Note that HTTP is also known as the stateless protocol.

On the other hand, HTTPS is the short form of HyperText Transport Protocol Secure. This protocol establishes secured transactions by encrypting data using SSL encryption. This is how data is protected using HTTPS while transferring it through the internet.

9. What is a Linked List?

A linked list is essentially a data structure that has a linear property. This data structure has a chain of connected nodes. Note that each node has data as well as the address of the following code. There are many types of linked lists, such as doubly, singly, and circular.

10. What is the use of a Break Statement?

We use a break statement to stop the execution of a loop once conditions are fulfilled. So the program will move to the following statement for execution.

11. What are the Software Development Life Cycle (SDLC) phases?

There are totally six phases in every software development lifecycle. They can be listed as follows:

• Planning and Analysis
• Design
• Development
• Testing
• Deployment
• Maintenance

12. Explain: OOPs Concepts

OOPs refers to Object Oriented Programming. OOPs is the methodology that supports software design based on data rather than logic and functions

Abstraction, polymorphism, inheritance, and encapsulation are the four OOPS concepts.

Abstraction: According to this OOPs concept, only the essential features of an object are shown to users. All the other information will be hidden. In other words, users will get only the information that they need.

Polymorphism: it is the ability of the data to take multiple forms based on various scenarios.

Inheritance: It represents the relationship between two classes – parent class and child class. According to this concept, the child class inherits the properties of the parent class.

Encapsulation: It is the process of wrapping data and functions in a single unit.        

13. Differentiate: Interface class with Abstract Class

Interface Class	Abstract Class
It can extend another interface	It can extend another class
An abstract is optional if you want to declare a method	An abstract is mandatory if you want to declare a method

14. What do you mean by OSI Model, and describe its various layers?

OSI is the short form of  Open Systems Interconnection. OSI Model has a seven-layer architecture that transports data from one point to another. Of the seven layers, the transport layer is the heart of the OSI Model. The presentation, application, and session layers are known as software layers. And data link layer, network layer, and physical layer are known as hardware layers.

15.How is IPv4 different from IPV6?

IPv4 is Internet Protocol version 4, whereas IPv6 is Internet Protocol version 6. In many ways, IPv6 is a better protocol than IPv4. IPv4 has a 32-bit address length, whereas IPv6 has a 128-bit one. IPv4 supports DHCP address configuration, whereas IPv6 supports renumbering address configuration. Moreover, Encryption and authentication are not supported in IPv4. On the other hand, they are supported in IPv6.

16. What is Serialization and deserialization?

It is the process of converting an object into a stream of bytes. So you can store the object in an easily transmittable way. You can move to another data store or destination or application effortlessly.

On the contrary, deserialization is the process of converting the streams of bytes into objects.

20. Differentiate Pre-emptive Scheduling and Non-preemptive Scheduling

Pre-emptive Scheduling	Non-preemptive Scheduling
When a priority task arrives, the current execution is halted, and the priority task is executed. It means You can interrupt processes	When a priority task arrives, the current process is unaffected. It means, Interruption is not allowed
It offers high flexibility	It doesn't provide flexibility
It includes overheads to organize procedures	It doesn't support overhead
You can utilize the CPU to maximum efficiency	CPU cannot be utilized beyond a limit

Mindtree Interview Questions for Advanced Learners

21. is ‘C’ language called Procedural language?

‘C’ is the programming language that executes functions based on procedures. Functions are nothing but parts of the main program. Procedural languages allow executing functions in a certain order to complete the program execution. So they don't respond to events in the middle of execution for any reason. That's why C is known as one of the procedural languages.

22. How can you avoid Structure Padding in C?

We can avoid structure padding in the following ways.

• Using  #pragma pack (1 ) directive
• Using attribute
• Avoiding relying on the structure layout
• Initializing padding bits with zero

23. What are the applications of different Data Structures

Know that array, heap, Linked list,  Hash Tables, Matrices, Vectors,  and Trees are a few data structures.

When it comes to arrays, they act as primitive building blocks to create other data structures.

When it comes to the linked list, they are used to switch applications and programs in the OS.

When it comes to trees, they help to manage database indexes. Moreover, the heap data structure stores Java objects in Java Virtual Machine.

24. What are the Key differences between White Box testing, Black Box testing, and Grey Box testing?

In the White box testing, the internal details such as code structure and internal paths are closely analyzed. Clear box testing, glass box testing, open box testing, and transparent box testing are the other names of white box testing.

In Black box testing, the internal details of a software program are not analyzed. Only the input and output values are analyzed.

Grey box testing is also known as integrated testing. This testing is the integrated version of white box testing and black box testing.

25. How will you pass data from one JSP to another?

You can pass data from one JSP to another in the following ways.

• Using Query Parameter
• Using Hidden Variable
• Using Session Object

26. What is the use of ABAP Queries?

We can create reports in the SAP application using ABAP queries. Mainly, ABAP queries create reports that do not already exist in the SAP application. you can create reports like basic lists and ranked lists with the help of ABAP queries. Note that every ABAP component has four components such as queries, user groups,infosets,and translation of query.

27. Differentiate: ‘Call by value’ and ‘Call by Reference’.

Call by Value	Call by Reference
The original value is not modified in this method	The original value is modified in this method
Only a copy of the variable is passed	The variable itself is passed
It is set as the default method in various programming languages such as VB Net, C++, and C#.	It is the method used in Java programs.
Variables are passed using simple methods.	We use Pointers to store the address of variables.

28. How is Static Library Linking different from Dynamic Library Linking?

Static Library Linking	Dynamic Library Linking
We use Linkers to perform static linking. It is generally done at the end of the compilation process.	The operating system performs this linking only at the run time.
These files are usually larger since executable files comprise all external programs.	The file size is small since a single shared file is stored in memory.
Programs run faster in this linking type.	Programs run slowly when compared to static linking.
The programs in the executable file don’t encounter compatibility issues because all codes are included in a single file.	This linking type faces compatibility issues at times.

29. How will you declare a variable that holds String values?

Know that a single char keyword can hold a single string value at a time. If you want to hold many string values, you need to create an array of characters. For example, if you make an array like  "char NewName [10];", you can hold up to 10 names. Here, we have declared the string variable as ‘NewName’.

30. Compare Checked and Unchecked Exceptions in Java.

Checked exceptions are checked during compilation time. On the other hand, unchecked exceptions are checked during run time.

Checked exceptions allow using the ‘try-catch’ or ‘throws’ keywords. On the contrary, unchecked exceptions don't allow using these keywords.

Checked exceptions include all exceptions other than subclasses, RuntTimeException, and errors. On the other hand, unchecked exceptions include RuntTimeException as well as subclasses.
