The first round was with HR, which went for 30 min. Before the HR interview, the recruiter asked me to send an email explaining my experience with Python, R, SQL, ML – regression, classification, decision trees, xgboost, random forest, gradient boosting, ensemble learning, Deep learning, Neural Networks, NLP, SAS, Java, forecasting etc. She also asked me to describe 2 projects i had worked on. I thought sending all these through email was really weird. After the HR call, I got informed about the second round the same day. The second round was with a Data Scientist, which went on for 45 min. Questions included basic SQL and ML. The second round was conducted by an inexperienced employee who asked me to write a SQL code over the phone with no screen sharing. The questions were easy, but coding without sharing the screen can be confusing. The interviewer was so unprofessional and unprepared, she wasn't even sure what role she was interviewing me for and didn't have my updated resume. I was very disappointed this came from Visa.
