I applied online.

The position was in Dublin, but I interviewed with someone on the West Coast, which was where I was located at the time.

The tech question round was multi-leveled, as in build X, then add Y, then adapt for Z. Essentially, based on whatever "system", add these functions and change them to handle the input/output/question of the system.

The interviewer was nice and better than one to two other companies I'd interviewed with in regards to responsiveness, communication, friendliness, etc.

Given a "system", build one function, then add another, then adapt and build something else. From a design-build problem, it was actually rather pleasant; the issue is that you spend a lot of time expecting interview questions and get tripped up on solving the "real-world problem" they give you.
