Pros
I had just finished university, and then it is often difficult to immediately find a good assignment/job that dares to do it with you. And Working Talent knows exactly how difficult that can be for that kind of (newly) employed person. From the start, I always had a good feeling with everyone in the organisation, and genuinely felt that they wanted to help me and were there for me. Joined a nice client through them, where I spent a year, and am now continuing on. Definitely a good start for people who want to work in Tech, and don't know exactly how to start yet.
Cons
In the beginning of my traineeship, I was switched a lot between account managers, and different people within the organisation when looking for a client. After that start went fine, but it would have been nicer if I clearly had 1 point of contact, and not switched from different people.
