Walmart Software Developer interview questions

I had onsite interview with 3 groups from eCommerice team and one lunch interview. In the first interview, he gave me an array and asked me to keep the largest number in the array in the first index whenever we add a new value to the array. (I was confused by this question because it was too easy and I didn't know whether this is what he wanted). Then he asked me to implement a heap using the array he gave me. Then he asked leetcode question, Word Search

5 week process 1)Phone with Recruiter - Messy, recruiter not organized, hard to schedule the call, had to postpone twice. 2)Hackerrank - Nice interviewer, easy OO problem. 3)Onsite - hard to schedule, hard to contact recruiter, not organized. - 4 interviews: 1 system design and 3 (some medium, some easy) leetcode style problems. I was thrown an extra one at the end. 4) Rejection after 2 days - I did very well in the onsite: solved all the problems and had nice conversations/clicked with everyone but was told they were looking for someone more senior. They should have challenged me more or asked better questions if they wanted to gauge my level, not trap me into problems that juniors can solve.
