Walmart conducted a hiring drive for IN3/IN4 SWE roles in . I have 3.5 years of experience and I was interviewing for the IN3 Software Engineer III position.

The interview process consisted of four rounds:

• Round 1: DSA round (60 minutes)

  • Shortest Path in Binary Matrix (Leetcode)

• Round 2: Core Java + LLD round (~70 minutes)

  • Questions about my current project
  • Basic questions on core Java, Streams API, and Collections
  • SOLID principles
  • Questions on executor service, IOC, and Dependency Injection
  • Questions on Spring Boot annotations
  • Singleton, Factory, Observer, Command, and other design patterns
  • LLD of a library management system (Class diagram and DB schema only)

• Round 3: Hiring Manager (HM) round (60 minutes)

  • Deep dive into my current and past projects
  • Discussion on design choices and trade-offs in my current project
  • Design of an order management system (Key components, API contracts, and DB design only)
  • Discussion on bloom filters and their practical use cases

• Round 4: HR round (30 minutes)

  • Current role and responsibilities
  • Why I want to join Walmart

I was surprised by the design discussion in the HM round. There was a communication gap between the recruiters and the candidates. One interviewer was very polite, but another was arrogant because I didn't give the solution he had in mind.

I received a verbal offer within 15 days.
