RBC Senior Applications Developer interview questions

Interview process was good but really slow. Initially, after my application they sent "Screening Sample Test" . The tests contains 2 questions and after completing that they get back to me after 10 days. and schedule in person technical interview with 2 people. Interview was good but the development manager was so hard on the questions and he was more interested about what you don't know rather than what I know. But it was a good experience. There were around 4 technical exercises to go through. Questions was about passing a parameters by value and by reference. Whats the contains method in the list do. UML diagram based on the customer accounts and trade, find all the trades based on the customerId. SOLID principle and many more.
