ExxonMobil Data Scientist interview questions

phone interview during 45mins. They usually tested my research and experience. They want to know about what can i do in the company. and also they want to know about the general question is what is your strong background or what is you weakness.

it's a technical intervview based on skype business with two guys from usa and singapore. They are quite nice and polite. The guy from the states seems a senior data scientist asked questions like project experience of classification regression, pca clustering and why not using this or that most questions based on what you did and why you made that decision.
