ING Data Scientist interview questions

The first mail the HR sent me included these questions: 1) What is the most impressive achievement you have realised? (e.g., medallist in math/informatics olympiad, winning a Kaggle competition, authoring a widely used Python or R-package, PhD at Ivy-league university, winning a Piano competition, ...) 2) Which technical/scientific discovery/method that you have developed are you most proud of in either supervised learning or unsupervised learning (or both)? 3)What salary are you looking for? 4) Which languages do you speak? 5) Did you deliver any contributions to open-source machine learning libraries? Or are there any contributions you really liked? 6) What’s your best example when you described something technical……to a non technical? The technical interview consisted of: - my background, - interpersonal skills, - a real life case study.
