Interview preparation tips for other job seekers - Be genuine about how much you know. Interviewer will ask to introduce candidates and will ask how much they know about Data Science and how much does the candidate rank themselves on a scale of 10 in Python & SQL
JD does mention about TensorFlow and R, but those languages are not important and are only an advantage to the candidate's profile. Mainly the interviewer will be looking for someone who has a decent programming skill and knows about regression models which is very important.
There will be 2 Interviewers one of them will be asking Python & Regression model questions and the other one SQL ones along with Power BI and Tableau overview
