I was contacted by a recruiter.

The process took two weeks.

I had a phone screen with a senior engineer. He gave me a technical question, and I solved it without issue. We talked about possible optimizations and the running time/space complexity.

I believe he wanted me to solve it in a different way, as he was asking me to describe the running complexity in terms of a graph. This confused me a bit since I wasn't thinking in terms of a graph. He didn't seem impressed by my answers.

Given a link to a website and helper functions, print the title of the linked page and all the titles of the page's links, and so on.
