I tried to use them but they keep changing the jobs too often. When I applied and interviewed for job "A" which paid 12,500 yuan per month, they told me it was "already filled" and tried really hard to push me to accept job "B" which paid 7,000 yuan per month as a "temporary solution". This did not seem right to me. I told them to call me only if they have a position that pays more than 12,000 yuan per month but they spam me every day with jobs that do not fit my requirements. Very unprofessional in my opinion.
