Xandr Software Engineer(Internship) interview questions

Engineering Intern position in Portland, WA. Wasn't actually sent a rejection email. I assume that I was rejected and ghosted because I have not heard back despite it being 2 months after the interview. My follow-up emails have been ignored. Recruiters took a really long time to schedule the initial interview, (1 week to reply to emails) 1 first round 60 minute interview. First part of the interview is a 30 minute presentation on teaching a technical topic. Afterwards a 30 minute technical phone screen. My experience during the interview itself was positive. My interviewer seemed genuinely interested in getting to know me and was happy to answer my questions about the company. Not sure why I was ghosted since my interviewer seemed very happy with my performance during the interview, but it is what it is.
