Top 10 Tech Mahindra Technical Interview Questions and Answers

 

Despite the fact that information technology or IT companies have expanded quite quickly in recent years, notably in India, very few of them are able to provide long-term employment to their employees. For this reason, people favour working for reputable businesses. Being affiliated with a brand gives you confidence that your career is on the correct track and might help you maintain some level of job security. People believe that working with Tech Mahindra will enable them to advance in their careers while also preserving a positive work-life balance.

 

This article offers a route for both experienced and new candidates to land their ideal job at Tech Mahindra, in addition to explaining how to respond to pertinent Tech Mahindra interview questions.

 

Common Tech Mahindra Java Interview Questions 

 

1. What is your take on factory design patterns?

Answer: The factory method pattern is a conceptual pattern used in class-based programming to solve the issue of creating an object without being required to specify the precise class of the new object. In order to achieve this, objects are created by calling factory methods rather than constructors. Either factory methods are specified in an interface & defined by subclasses, or they are defined in a base class and may be modified by subclasses.

 

2. Trunk-based development: what is it?

Answer: A single trunk, commonly referred to as the trunk, master, or main, is where the majority of the work is done under the branching paradigm known as trunk-based development. All team members provide daily merges to the trunk.

 

Because it makes version control simpler, trunk-based development is a well-liked development model. This model reduces the likelihood of merging disputes because the trunk is the only reliable source of information.

 

3. What distinguishes continuous integration, delivery and deployment?

Answer: The series of actions necessary to create and test the project are carried out using continuous integration (CI). Every time a change is committed to a shared repository, CI automatically runs, providing developers with immediate feedback on the project's status.

Continuous delivery is a development of CI. Its objective is to fully automate the process of packaging and releasing software. A deployable binary, package, or container is the result of a continuous delivery pipeline.

A logical progression from continuous delivery is continuous deployment. It is a procedure that automatically and safely deploys the output from the delivery pipeline to the production system.

 

3. Provide the TDD concept.

Answer: In the process of Test-Driven Development (TDD), tests are written before the actual code is written. Developers can think about problems in terms of inputs and outputs and design more testable (and hence more modular) code by reversing the typical order in which software is written.

Three steps make up the TDD cycle:

• Red: It creates a failing test.
• Green: It creates the bare minimum of code to pass the test.
• Refactoring: It involves making the code more readable, abstract, and efficient.

 

4. What distinguishes acceptance testing from end-to-end testing?

Answer: End-to-end testing typically entails simulating user interaction through the UI in order to test the application. End-to-end testing gives developers the most assurance that the system is operating properly because it necessitates that the application executes in a fully production-like environment.

 

Whereas verifying acceptance criteria is done through acceptance testing. Acceptance criteria are a list of the guidelines and actions that the programme must take to satisfy the needs of the users. By definition, an application that satisfies all requirements also satisfies the users' business requirements.

Tech Mahindra Telephonic Interview Questions

 

 

1. In multiprogramming time-sharing systems, what is reentrancy?

Answer: Reentrancy is a particularly successful memory-saving technique for multiprogramming time-sharing systems. It has the capacity to enable several users to simultaneously share a single copy of the programme.

Its two key characteristics are as follows:

 

• The software code is unable to change itself.
• Local data for each user process gets saved separately.

 

2. What is the local variables' default value in Java?

Answer: Java does not initialize local variables, primitives, or object references with any predetermined default value.

 

3. Why do DBMS employ checkpoints?

Answer: In the event that the database experiences an unexpected shutdown, a checkpoint is used for recovery. The dirty pages (modified pages) from the logs relay, or from a buffer to the physical disc, are written by checkpoints at specific intervals. It is often referred to as "dirty pages hardening."

 

Let us quickly address two commonly asked questions that are non-technical but at the same time can prove to be very tricky. You must answer them cautiously.

 

Here is the first question:

 

1. What draws you to Tech Mahindra as a job candidate?

It provides a great work environment, a warm setting, and a pleasant attitude that is good for both individual and business growth.

 

2. Are you willing to relocate to different parts of India?

 

Don't respond negatively. You would typically be asked to move if a project requirement existed. So you will always benefit from learning more about the projects. Be ready to respond positively and express your concerns to the recruiter.
