Walmart Data Scientist interview questions

After sending out my resume, I was contacted my a company recruiter. We had a great conversation. The recruiter was very friendly and knowledgeable. We talked about Walmart's advantages with enormous amount of data and I was very excited. It took a big turn when I talked to one of their "engineers", he was very rude: constantly interrupted me and didn't have a clue about what he was talking about, unable to communicate and didn't know what a data scientist do. The worst interviewer ever. I feel sorry for his co-workers. He should be fired from his position.
