1 screening round 4 onsite - one hour each 1 python data manipulation round with stats questions 1 sql round 1 causal modeling case study round 1 machine learning round

It started with basic introduction and started discussing about one of my projects. The interviewer doesn't look very much deep technical interview Data Science and was asking same question again and again. She looks very confusing. However, surprisingly the interview went started at 1PM Abd went till 2:10 PM. I have got the rejected email at 1:51 PM which is 29 minutes before the interview ended. Very much unprofessional and confused interviewer.
