As is the norm, the HR rounds are conducted to ensure that you’re a cultural fit for the company. To nail these interviews, you’ll need to express your desire to join Walmart. You can also be asked Walmart software engineer interview questions based on the company’s history, values, goals, and objectives.
Don’t make the mistake of underestimating this round because this might just lead to you not getting hired. Keep in mind that even your physical presence, how you behave, and your attitude throughout will be monitored.
So be pleasant, cordial, and prepared to face puzzle-based questions that’ll test your overall intelligence and ability to adapt to challenging situations.

A memory leak is created when programmers develop a heap memory and then don’t destroy it. As a result of this memory leak, the computer’s performance suffers since the usable memory is decreased.
The worst-case scenario is that a lot of the memory that’s available may be allocated and cause all or part of the system to stop working properly. These leaks can be problematic when it comes to applications such as daemons and servers that, by definition, are never terminated.
To avoid memory leaks, it's always advised to destroy heap memory when it's not required.

Candidate key: A candidate key is a particular attribute or group of attributes that uniquely identify a tuple in a way that no subset can uniquely identify a tuple. A candidate key can also be known as a subset of super keys. Out of all the candidate keys, a key is selected and called the primary key.
Foreign key: A foreign key is a column in a table that indicates the primary key of another table. For instance, in a company, each employee is given a specific department, and a department and an employee are two separate entities. So, the department’s information can’t be kept in the personnel table, which is why the primary key of one table is used to join or relate these two tables.
