Hi Sir/Ms, I’ve scrolled & checked in Maukerja jobs and in my job timeline, I’ve barely see job that requiring for mandarin speaker however maybe the type of job that we’re looking for is different. Sometimes, a few jobs that requires to speak three language, so that’s why you see most of the job require to speak in other language. Other than that, i recommend for you to give feedback in the apps Maukerja. Over there, you can directly contact the customer service and state your concerns.

i hope my answer helps you.
