One hour technical interview and then three rounds onsite. The recruiters were not responsive and never replied emails. The onsite experience was horrible. The hiring manager was very unprofessional. No eye contacts during the entire 45-minute interview. The case interviews were based on their past projects. The project itself was pretty boring. The interviewer kept asking why it was a data science project. The questions they asked about machine learning were not clear and they didn't accept alternative methods. I would avoid wasting time with them.
