I chose Zebra People to represent me while looking for UX/UI roles. I met them first at their office and they spent about an hour going through my portofolio and telling me how I could improve it. I then met them a second time and we revised my portfolio again. There were several emails back and forth and within a short amount of time I was being offered many roles. The whole process was very friendly, not intimidating and very helpful in helping me how to present myself and my work.
