IBM Software Intern interview questions

I prepared using leetcode, and when the interview started i was given an online OA where there was a medium leetocode problem. I got it mostly correct, but I think I took too long which is why I was rejected.

Techincal Interview 2 leet code easy-medium q's. And a bunch of questions about graph theory and solving problems. Leetcode questions were pretty tuff I don't remember all but one was a graph traversal and one was linked list
