Qualtrics Network Engineer interview questions

The interview process took less than two weeks. Initial phone call was introductory with HR for 20 mins. The 2nd interview was with the hiring manager which lasted for 30 mins. This included 3-4 behavioral questions and 1 very basic technical question. The call with hiring manager was very easy and questions were not difficult at all and I think I did very well. However, I got a rejection in less than 24 hours !
