Had an interview for a graduate job in Dublin. The whole process involved a group of students going through various activities, such as a group discussion, coding test, and an interview.

During the interview, I was asked reasonable questions, such as, "What is the difference between an inner and an outer join in SQL?"

The whole process took about 4 hours, with a lunch break. Everyone was at ease, welcoming, and not intimidating.

Had a great impression of a well-organized company.

What is the difference between an inner and outer join in SQL?

What classes, including data members and methods, would you design for a coffee machine?
