Qualtrics Software Engineer Internship interview questions

I submitted the resume through the company website and got two rounds of phone interviews in this August and September. All of them are technical interviews and the questions are medium level problems from leetcode.

I applied online and was referred by an acquaintance who works there. Once the referral when thought I was contacted by a recruiter to set up the first interview. I had a total of two interviews both with different software engineers from the Provo and Seattle offices. Both interviews started with discussing a recent project and then when into the technical problems. Both problems seemed to be medium to hard leetcode questions. In the first interview I was able to complete the problem, and in the second interview, due to time constraints, I wasn't able to fully implement my pseudo code but had my plan clearly laid out. That didn't seem to be satisfactory however and I received a rejection email shortly after the interview.
