Confluent Intern interview questions

One video phone call. I found him to be actually very rude, extremely disinterested, and eager to leave. He actually hung up the call without even saying goodbye? Very difficult to talk to, I'm surprised he's interviewing interns.

Phone Interview-- no Hackerrank. I was a bit confused as to why they wanted to interview me cause it was for a position that i was nowhere near qualified for. Overall, I thought it was a bit disorganized, but looking back the questions werent that bad if you already taken algorithm/data structure classes.
