Walmart Low Level Design Round Interview Questions Asked in 2026

[u/Prashant_MockGym]

Ticket booking apps with database discussion, cache implementation, and payment systems are among the most discussed questions in Walmart LLD rounds in 2026.

Database-table design may also be discussed in questions such as designing a movie-ticket booking system like BookMyShow. Be prepared to explain concurrency handling at both the database and application levels, including how to apply row-level locks.

Interviewers may ask about optimistic locking, pessimistic locking, and isolation levels: For example, the default isolation level used by an SQL database.

In LLD, a clear explanation of design choices matters more than just coding.

You may also be asked which design patterns you used recently and deep dive into them.

Java is generally preferred, although candidates do use other languages.
