Walmart Senior UX Designer interview questions

First, they asked me to do a design task, which is nothing but a Heuristic Evaluation of the website and a redesign of Product design and product listing pages. Completed the task and they scheduled the first round where the interviewer didn't listen to anything that I told, instead that person was preaching his ideologies. Although I've applied for a UX Design role, the interviewer was asking questions about user research. Overall the experience was really bad and he didn't show kindness the go through the design exercise as it took 8-10 hrs to complete.
