Solicité el puesto a través de la recomendación de un empleado. Acudí a una entrevista en Walmart Global Tech (Bengaluru) en jul 2020
Entrevista
After clearing an online test, they literally took interview rounds for a whole day and yet no one even has a courtesy to give feedback. HRs also ignore your calls once you are done with the interview process. They do not understand that everyones time is important and if you have taken someone's time to conduct these many rounds, it is a minimum courtesy to atleast let the interviewee know the result of it!
The interview process was smooth and well organized. It started with an initial recruiter screening, followed by a technical assessment focused on coding, problem-solving, Java backend concepts, data structures, and system design basics. The interviewer was professional, explained the expectations clearly, and gave time to discuss my approach before coding.

The process included several stages. The first interview was a 30-minute conversation with recruiting. The second interview was a one-hour technical interview focused mainly on technical questions related to the role. The final technical interview lasted around one hour and included several participants. During that session, I completed a small live coding exercise in C# focused on problem-solving and logic, followed by a system design exercise where I had to propose the architecture for a system. After that, they asked additional technical questions. The last stage was an in-person behavioral interview focused mainly on communication, experience, and culture fit.
