Mindtree interview consists of three rounds: online assessment, technical interviews, and HR interviews.
Let’s look into the rounds deeply one by one.
In this round, you will be asked various questions from the following three sections to test your quantitative, written English, and coding ability.
Quantitative: The assessment will include questions to check your quantitative and analytical skills. No doubt you must be quick and accurate to clear this round.
Written English: The assessment will include questions to test your knowledge of English tense forms, prepositions, antonyms, synonyms, etc. Additionally, you will also be asked to write a few short passages to test your writing abilities.
Coding: The assessment will have questions to code for at least two problems. The difficulty level of the coding would be either easy or medium, but there won't be any need for complex coding. Mainly, you will be asked to write codes in C, Python, or C++ languages. To clear this round, you must be familiar with programming.
Only when you clear the online assessment you will be allowed to attend the technical interview. In this round, your technical expertise will be tested in-depth. You will be asked questions about your previous experience, projects worked on, and achievements.
To clear this round successfully, you must be thorough in computer fundamentals, including data structures and algorithms, computer networks, operating systems, etc. Mainly, you must have expertise in programming languages such as C, Python, and C++. This round may have additional rounds based on the performance of your initial rounds.
It is one of the key rounds of the Mindtree interview process. Even if you have attended technical rounds successfully, you must tackle this round intelligently. In this round, they will test your attitude, problem-solving skills, and stress management in many ways. To pass this round successfully, you must know Mindtree’s core values, leadership principles, culture, etc.

Modules are essentially Python files that come with .py extensions. The files may have classes as well as functions. A module can import other modules as objects. We use the import statement for the same.
When it comes to packages, it is a folder or directory. A package may contain sub-packages and modules.
Packages eliminate clashes between module names. They support the hierarchical structuring of module namespaces using dot notation. Besides, we can quickly create packages in Python.
Know that Python maintains a namespace in dictionaries. We use Namespaces to ensure every object in a Python program has a unique name. As a result, it eliminates name conflicts between objects.
Following are the different types of namespaces.
It is essentially an environment variable used to add directories when importing a package or module. The interpreter uses this variable to determine the module that must be loaded. A Python program can access these modules and packages. It is possible to use PYTHONPATH to ensure that the imported files exist in the directories. Besides, PYTHONPATH helps maintain libraries we don't install in the global default location.
The help function displays the documentation of functions, modules, etc. If we don’t pass an argument in this function, then the help utility is initiated in the console.
The dir () function returns a valid list of attributes in addition to method objects. But it works differently for various objects. When it comes to module objects, it returns a list of attributes. Similarly, when it comes to class objects, it returns a list of valid attributes along with base attributes. If we don’t pass any argument, it returns a list of attributes in the current scope.
An iterator is nothing but an object that remembers its state. With iterators, we can iterate over strings, lists, etc. We use the _iter_ ( ) method to initialize iterators.
Literals are nothing but a value or data assigned to a variable. There are many types of literals, as shown below:
It is a block of code we can use in a program as and when required. A function contains an arguments list, a valid name, and a body. The main thing is that functions simplify modular programming. When it comes to Python, it provides many built-in functions. Not only that, it allows users to build their own functions as well.
In Python, there are three types of functions.
We use the 'remove ( )' function to delete a specific data element from a list regardless of location. On the other hand, we can use the 'del' statement to delete a data element in a specific location in a list. The index value is used to specify the element's location in the del function.
It is the ability of data to keep up its consistency and accuracy throughout its lifecycle. It is one of the crucial aspects considered in software design in addition to implementation.
WHERE, GROUP BY, ORDER BY, and HAVING are the clauses used with SELECT statements.
We use the WHERE clause to filter records based on certain conditions.
GROUP BY clause can be used to group records based on identical data. It is typically used with aggregate functions and generates summarized results.
We will use the ORDER BY clause to sort field records in ascending or descending order.
We use the HAVING clause and the GROUP BY clause to filter records in a table. It is essential to note that the WHERE clause is entirely different from the HAVING clause because we use the HAVING clause to filter aggregated records.

One-to-one: It is a relationship made between two tables. It means that a record in a table is associated with a record in another table.
Many-to-one: It is similar to the previous one. Many records in tables are associated with a single record in a table.
One-to-many: It is a relationship made between a record in a table and multiple records in other tables.
SQL is a query language that performs various operations in a database. Jotted down are the uses of SQL.
In pattern matching, wildcards are used instead of writing the exact word. We can use the LIKE operator with wildcards to retrieve the required data.
There are four ways by which we can fetch the required data.
UDF or User-Defined Function helps to create functions using SQL expressions. User-defined functions accept parameters, perform operations, and return a value. We can define UDF in two ways: persistent and temporary. We can reuse a persistent UDF in multiple queries and use a temporary UDF in a single query.
Furthermore, UDFs provide many benefits, such as quick execution, modular programming, and reduced network traffic.
Two types of user-defined functions are denoted below:
No. A NULL value is not equivalent to a zero or blank space. This is because NULL is the unavailable value for performing arithmetic operations. We can consider a NULL value as a missing value or unknown value.
|We use this statement to remove all table rows.||We use this command to remove specific rows of a table.|
|It is a DDL statement||It is a DML statement|
|The WHERE clause is not used.||The WHERE clause is used.|
|It doesn’t support indexed views.||It supports indexed views.|
|It uses a dynamic schema.||It uses a predefined schema.|
|It takes work to process complex queries.||Complex queries can be quickly processed.|
|Scaling is done horizontally. So, we must add more servers to balance loads.||Scaling is done vertically. So we need to add SSDs and RAMs to balance loads.|
|It supports CAP Theorem. CAP stands for Consistency, Availability, along with Partition tolerance.||It supports ACID properties.|
ClassLoader is nothing but a subsystem of JVM. It loads the required interfaces and classes to the JVM when needed.
There are totally three built-in classloaders in Java as follows:
JVM stands for Java Virtual Machine. It is a runtime engine that enables a computer to run Java programs. It is achieved by converting Java codes into byte codes. In other words, the JVM loads, examines, and executes codes. Also, JVM calls the main method in a Java program.
A thread in Java goes through various stages throughout its lifecycle. Below are the multiple stages of a Java thread lifecycle.
It is the variable declared only in the class itself. No other instance cannot use the variable. Simply put, only one copy of the variable is available in memory, no matter how many class instances are created. The main thing about using a static variable is that it simplifies memory management. Simply put, it makes a Java program memory-efficient.
Access specifiers are nothing but keywords. They help to define the access scope of a method, class, or variable.
Java comes with four access specifiers, as mentioned below:
|Instance method||Static method|
|It is a method that is not declared static.||It is a method declared static.|
|We do need objects to call static methods.||Objects are not required to call static methods|
|Both static as well as non-static variables can access instance methods||Non-static variables cannot access static methods|
No. It is not possible to declare a constructor as final. This is because constructors never inherit. If we declare a constructor, the compiler will throw an error definitely.
|Checked exceptions||Unchecked exceptions|
|They are checked during the time of compilation.||They are checked during the time of execution.|
|They support using ‘throws’ keywords.||They don’t support using these keywords.|
|They are the subclass of the exception classes.||They are not part of the exception classes since they are runtime exceptions|
|The JVM needs the exception to handle these exceptions.||The JVM doesn’t need the exception for the same.|
|FileNotFoundException and IOException are checked exceptions.||ArithmeticException and NullPointerException are unchecked exceptions.|
The useState ( ) is nothing but a built-in React hook. It allows having state variables in functional components. In other words, it will enable tracking state in a function component. Here, the state denotes the data that needs tracking in applications.
This hook typically returns an array with two values. One value is the current state, and another is the function needed to update the state. Besides, we can use this hook when the DOM is manipulating something dynamically.
Every component in ReactJS contains the built-in state object. This object has all the property values of the component.
In a way, state objects control the behavior of ReactJS components. If there is any change in any property value of a state object, then it leads to the re-rendering of the component.
We use props to pass data from the higher hierarchy to a component in a deeper order. The props can go deep until it reaches the required hierarchy level.

They are essentially built-in functions. It allows using state along with lifecycle methods in react components. As a result, we can improve the reuse of codes and navigate the component tree flexibly.
The main thing about react hooks is that we can use all the features of hooks without writing class components. In other words, we cannot use hooks in class components.
Re-rendering of a component occurs when props are changed. Not only components, but re-rendering may also happen in child components. If we don't update the re-rendering components, it will significantly affect the applications' performance.
We can prevent re-rendering using the ‘shouldComponentUpdate ( )’ method.
|We use react hooks in functional components.||We use classes in class-based react components.|
|It won’t require the declaration of constructors.||It is necessary to declare constructors inside class components|
|It doesn’t use the ‘this’ keyword in state declaration.||It uses the ‘this’ keyword for state declaration.|
|The ‘usestate’ feature makes react hooks ‘easy to use’.||No single function is used for ease of use.|
|It supports implementing context and Redux API.||Classes are not preferred for context and redux API.|
|Controlled Components||Uncontrolled Components|
|They are managed by React state. It means that their internal states don’t play any role||They are managed by their own internal states.|
|Data usually flows from the parent component to other components.||It flows within components.|
|The parent component controls data.||DOM controls data.|
|We can easily debug these components.||We cannot easily debug these components.|
|It has good control over the data.||It needs better control over data.|
|The complexity is less.||The complexity is high.|
|It does validation control.||It doesn’t do validation control.|
|It is faster.||It is slower.|
We can list the types of automation testing in functional and non-functional testing.
[Related Article: Automation Testing vs Manual Testing]
A test environment denotes a computer or a server. This is where developers or testes test software or a piece of software. The following are the necessary components of a test environment.
It is essential to know that users may use any web browser to run web applications. So we need to test web applications in all browsers to check their compatibility and adaptability. We can ensure that users get the same experience in any browser. Thus, we can achieve increased customer satisfaction and boom business productivity.
This testing is conducted to check whether a newly added feature in no way affects the performance of the software. We can use different frameworks and tools to conduct automated regression testing.
Here are the best practices that we should follow in automated testing.
Following is a brief of a few risks associated with automated testing.
It is an open-source automation framework widely used for testing robotic process automation. Most of the libraries of this framework are also open-source. Besides, it is a platform-independent tool that is built in Python.
No. We cannot automate the testing of CAPTCHA.
No. It is not possible to get 100% automated testing. Mainly, checking the background or using CAPTCHA will restrict the efficiency of automated testing. At this time, it is better to use manual testing.
With Power BI, we can:
In short, we can convert raw business data into valuable visual data. So we can make informed decisions.
Power pivot extends the analytical capabilities of MS Excel. Know that it is one of the add-ons offered by Microsoft Excel 2010.
Following are the filters used in Power BI.
The below graphic shows the different connectivity modes of Power BI.

Microsoft Azure is the cloud service associated with Power BI. Following are the locations where power BI data is stored.
We can resize a responsive slicer into various sizes and shapes. As we change the responsive slicer, the report's data also adjusts. Note that responsive slicers work in mob applications too.
|It can handle a large amount of data.||It can handle only a limited amount of data.|
|It is the best tool for experts.||It is the best tool for novices and experts.|
|UI is user-friendly. It comes with drag-and-drop features.||UI is complex when compared with Power BI. It provides powerful features|
|It uses MAX for the same.||It uses DAX for measures as well as dimensions.|
|It connects with most databases in addition to web services.||It is mainly used with SQL servers and MS Excel.|
|It offers good customization features.||Customization options are limited.|
When prepackaged files are insufficient, we use custom visual files. Custom files can be created and imported as we perform for prepackaged files.
We can use a data editor to manage rows and columns of data. In other words, it allows the reshaping of data smoothly.
