PubMatic Software Engineer Intern interview questions

There was an initial screening round, after which I had an online data structures and algorithm interview where I was asked to split sentences which has no spaces into individual words which make sense. I was later called onsite where I was shown their building and I had another technical interview where I was asked some AI concepts, and an LRU cache design. The next round was with the VP where I was asked a leetcode question on to find the maximum length of a palindrome string. They seemed pretty positive and then they said they were moving forward with another candidate after a week.
