Interview
1 Screening interview
6 Full-loop interviews including coding, basic ml, 2 research oriented, behavioral, research presentation.
After the screening, you will get noticed to conduct the full-loop interviews. For coding, you don't have to worry about leetcode-type question - it is more related to your research based coding questions. For research oriented question, interviewers may ask challenging questions regarding the research topic that you have been studied.
For research presentation - you will have to prepare for 50min presentation regarding your research during your phd years.
