Snap Software Developer interview questions

The final round went fine there were 1 coding round of graph question, then a 30 minutes chat to ask about the company in another round. Snap also has a design round which is very strange to me given that I applied as a New grad and also the interviewer in that kept on changing requirements and asked me to develop ML server which I have no idea about, and was also not sitting in a very good environment as her wife/girlfriend kept on working behind him which made hard to concentrate.
