I would honestly say, this is one of my very dissatisfying and worst interview session in my entire 10+ year career. I was approached by an internal HR member who was prompt and nice enough in scheduling the interview for the UI engineer, But i felt that the technical interviewer himself was very arrogant and outrageous in his phone conversation right from the beginning. He called 30 mins later to the scheduled time, As soon as he called, he started pouring down questions one after the another with out any formal introduction or even checking what state i am in. Even though my resume boasted of designing UI for 20 AAA gaming titles, TV/Video UI for every major gaming console, mobile and web platforms with strong portfolio links, he reported to the recruiter that i lack basic skills and interest in UI . I even felt that he did not even go through my 10 page resume.Upon checking the interviewers's linkedin profile, I have noticed that he has not designed even a single UI in his careeer apart from vudu. He showed least interest in my vast experiences in video streaming and GUI including working for some big names like Microsoft, Verizon. At one point he even started ridiculing them. I think he was predetermined to reject me that day, he kept asking half baked questions and jumping to the next with out even listening completely as he showed least patience. so even after i cited references as the proof to my answers in the book(Elements of programming Interviews), he challenged that those answers are incorrect. Example Merging K Sorted lists( I gave him all 3 Heap/Priority Queue,Divide Conquer, Merge Sort approaches). None seemed to satisfy him even to the least, He did not consider they deserve partial credit , since he gave zero feed back to the recruiter about my coding abilities. Most of the time, he was bragging about himself, showing least interest in the other person. I wonder how a big company like walmart allows a single individual to be the supreme commander and the sole decision maker. I felt that that i would not have accepted the position, even if they did, offer, as their entire work culture, interview processes seemed very hostile and messed up. Heard of rumours about walmart's low wage and low level work ethics, Got a own experience and bitter taste of it for the first time
