eBay Software Engineer Internship interview questions

The recruiter asks about academic projects on my resume first. Then he gives me an algorithm problem. The whole phone interview last 45 minutes. I only have 20 minutes to solve the problem and the recruiter wasn't even listening to my elaborating of the thinking process.

Resume Screening and typical Hackerrank challenge with 5 problems. Then, I was invited to onsite interview. Mainly it was behavioral interview with questions about past projects and my role in it, as well as challenges that I have faced. Probably the reason for me being rejected is the language barrier.
