Experian PhD Data Science Intern interview questions

Online assessment with no coding. Some probability questions, two code complexity questions, some fundamental ML questions, AI query and techniques questions. For the second round I had a panel with 7 people. First you are asked to give a presentation on some project you worked on, answer questions along the way, then answer some basic ML questions (bagging vs boosting, auc roc, when and why use deep learning), then 2 coding questions sort of leetcode easy. Very friendly, warm and accommodating folks.
