Shopee Data Scientist interview questions

there are three rounds, the management of this start up company is not that nice. first round two colleagues ask some basic questions from machine learning , sql , big data and so on. then give you a mini project. second interview subitted code, description and slides to them and present the results to another two guys. third interview: one to one with team lead. She didnt ask hash questions and told I was profession and will be offered. After that totally no response. I tried to call hr who contacted me in this long period, and hr lady blocked my phone number ........ so interesting ....................
