After the first screening, we love to meet face to face, usually via a video call, so we can learn more about each other. If we see there is mutual interest, we'll ask you to spend more time with us, either by coming to our offices for a full day or going through our online assessment. Our goal is both to get to know your skills better and showcase our culture and way of work to you.
