First Derivatives Junior Software Engineer interview questions

Applied via the careers section on their website. Got a phone call asking whether I could complete an online programming test. This had some awkward questions like you'd see in Oracle's basic Java certification exams (e.g. identify errors that any IDE would highlight) but was ok overall. This lead to a phone interview with a senior developer. It was quite brief - some questions around OOP principles, experience working with 3rd party libraries (especially test frameworks like JUnit), how to approach fixing a bug, etc. The face to face interview was also quite straightforward. The format was a chat with a developer and a manager about my prior programming projects. Experience with DBs and finance concepts is a definite plus. There were also the usual questions about working in groups and demonstrating leadership. The entire interview process took around 2 weeks but it was a month before I heard back about an offer, which I declined due to accepting a position elsewhere.
