payment pay on time!
By Jasmine T.
Communicate and response time varied and often the workflow not clear. Application process and hiring manager communication specifically could be improved.
By customer
The system itself was well-designed and easy to use. However, there were instances where answers to specific questions were lacking, forcing everyone to proceed with their work based on guesswork. Another negative point was that many people who onboarded the project found it already closed, leaving them unable to start work and feeling confused.
By Rei
The payment was done within 1 month. The instructions were easy to understand.
By Mitsumi
A little slow to answer our questions, but otherwise ok.
By Maki H.
Overall good experience. During the project feedback was sufficient and escalation response time was good considering the time difference.

The remaning task was questionable.It was still tasks available, but the project was ended. This affected my feeling.
