We have used computer services from them in the past so were able to connect with our previous team members who are now at other companies within this industry (Competitor).
The benefits of being part-time/ freelance was very important because that is how I am paid currently by my current employer which works great! They did not provide any training or resources like tips sheets etc when they hired me previously but if you know what questions might be coming up during onboarding then maybe ask those ahead of time? This seems pretty standard across all offices these days - no extra perks added onto an hourly rate unless there's some sort of benefit offered through your employment contract e.g pension scheme contributions / share options.
