Worst experience ever.

First round was good. The interviewer was polite and humble, and asked about Java 8 and Spring Boot.

Second round was horrible!

The interviewer joined 10 minutes late. He was very rude and impolite from the beginning of the interview. He didn’t bother to introduce himself, so I'm unsure of his position.

While I was explaining my project, he interrupted me after every sentence, undermining everything I was explaining.

The kind of arguments he gave made me question his capability to conduct interviews.

He gave me a very vague problem statement. When I asked him follow-up questions, he reacted defensively and started shouting. He didn’t have a single clue about what he was speaking or expecting.

After 2-3 minutes, he refused to answer any questions and said I had 10 minutes to complete the task.

He stopped me abruptly after 2 minutes and said in a very arrogant tone that I was done.

I was very surprised by this extremely aggressive, arrogant, and unprofessional behavior from the interviewer. I didn’t expect this from a brand like Walmart.

A complete waste of a day!

Advice to Walmart: Please dedicate time to training your interviewers on professional interview behavior. Select individuals who are capable of conducting interviews.
