Walmart Recruitment Process

Walmart's interview process is comprehensive to shortlist the best candidates. You require strategic planning to crack the challenging Walmart job interview questions. While the exact interview process varies based on the role you apply for, the typical stages involved are as follows:

Online Application 

Walmart primarily accepts online applications. Any candidate interested in a position at Walmart can fill out their application forms online by visiting the official website. You can also find a hiring kiosk at customer service or at the Walmart store. 

Application Assessment 

If the recruiters find you to be a good match, they might send you an email. So, it is better to fill out the application in detail. The more the employer knows about you, the better. Still, your application selection largely depends on your professional experience and the other candidates vying for the position.

Recruiter Phone/Video Interview 

In a 30-minute round, the recruiter will assess your basic fit and professionalism. You can expect Walmart interview questions related to your CV in addition to some behavioral questions to gauge your soft skills. 

Online Assessment

In this stage of the Walmart interview process, you will be presented with 65 Walmart interview questions present in five sections. Each section evaluates your reactions to a particular situation. You will have hypothetical situations and questions to test your mathematical and logical skills, prioritization skills, and work style characteristics. 

The On-site or Telephonic Interview 

The next interview round involves in-depth technical and concept-related Walmart interview questions. The employer will assess your technical expertise relevant to the role. You will have to appear for four to five interview rounds. 

Coding Interview

This interview round is for those who apply for software engineering positions. It comprises a set of Walmart interview questions on coding in a given time frame (up to 60 minutes). The time allotted can vary based on the number and complexity of questions. It will either be a part of the on-site interview or a share-screen online interview. 

HR Interview 

The final round is the HR round comprising several behavioral questions. You should be prepared to discuss your past experience, answer hypothetical questions, and negotiate the final deal.

Once you are through with this, you'll have a drug and a background check, and if you pass both, you will be called for orientation. 

Walmart Technical Interview Questions and Answers

1. How would you define CASE tools? 

A computer-aided software engineering (CASE) tool is a complete software package that supports the design and implementation of information systems. It helps document a database design. It is ideal for maintaining the consistency of a design.

2. Do you think it is possible to execute several catch blocks for a try statement?

No, it isn’t because only one of the exceptions will be thrown.

3. What is the difference between queue and stack? 

Stacks

Queues

They are based on the LIFO principle, i.e., the last inserted element is the first to come out of the list.

They are based on the FIFO principle, i.eThe first inserted element is the first to come out of the list.

Insertion and deletion are possible only from the top of the list.

Insertion and deletion are possible from the opposite ends of the list. While insertion occurs at the rear of the list, the deletion takes place from the front.

Insert operation is termed as the push operation.

Insert operation is termed as the enqueue operation.

Delete operation is the pop operation.

Delete operation is the dequeue operation.

Suitable for solving problems on recursion.

Suitable for solving problems with sequential processing.

It is a vertical collection visual.

It is a horizontal collection visual.

4. What is the difference between a thread and a process?

Process

Thread

It is a program in execution.

It is a segment of a process.

It takes more time to terminate.

It takes less time to terminate.

The process takes more time to create.

It takes less time. 

Context switching takes more time.

It takes less time. 

It is less efficient in terms of communication.

It is more efficient. 

It is isolated.

Thread shares a memory.

A child process is not affected by the changes to the parent process. 

All threads of the same process have the same address space and other resources. Thus, a change to the main thread affects the behavior of the other threads. 

The process involves a system call. 

Threads do not involve a system call. They are created using APIs.

5. What are memory leaks? How can they be avoided?

A memory leak develops when a programmer creates a heap memory and does not destroy it. A memory leak results in compromised computer performance as the amount of usable memory gets reduced. The best way to avoid memory leaks is to destroy a heap memory when it is no longer required.

6. What are wild pointers? 

Uninitialized pointers pointing to any arbitrary memory location are called wild pointers. They potentially cause a program to crash or behave improperly.

7. What do you understand about the Primary key and Super key in DBMS?  

Super Key: It is a collection of all the keys that allow a user to uniquely identify rows in a table. So, all columns that can uniquely identify the table's other columns are called super keys.

Primary Key: It is one of the candidate keys. It is a column or group of columns that help uniquely identify each record in a table, such that no subset can uniquely identify each tuple. A primary key constraint prevents null values or duplicates from appearing. 

8. What are preprocessors in the C programming language? 

Preprocessors are programs that process the source code before compilation. The different types of preprocessors directives are as follows:

  • Macros
  • File Inclusion
  • Header files
  • user-defined files
  • Conditional Compilation

9. What is multithreading? What are its advantages?

A thread is the smallest unit of processing. It is a lightweight sub-process. Multithreading is the process of running several threads simultaneously in a process. Dividing a process into various threads helps achieve parallelism. An example of multithreading is several tabs in a browser, each representing a thread. The advantages of multithreading are as follows:

  • Enhanced Responsiveness: It leads to increased responsiveness in the system because even if some threads get blocked, others continue their execution.
  • Less time to switch context: It happens because threads share the same data and code. 
  • Communication: Communication between the threads is faster because all the threads are present within one single process. 

10. What do you understand about abstraction and encapsulation?

Abstraction is a way of hiding unwanted information. Contrastingly, encapsulation is a way to hide the data in a single unit or entity along with a method to protect information from the outside. 

Abstraction

Encapsulation

It is the method of gaining information.

It is the method to contain the information.

Problems are solved at the design or interface level.

Problems are solved at the implementation level.

It is implemented using abstract classes and interfaces.

It is implemented using an access modifier. 

It gives access to specific parts of data.

It hides data, and the user can not access it directly.

It lays emphasis on “what” should be done.

It emphasizes “how” it is to be done.
