No hr/recruiter call/email or any introduction!They just sent you a case from a no reply email (about 3days workload) and asked you to finish then you can have a chance to talk to an employee. I searched Glassdoor when I received it, and all recent reviews mentioned they didn’t intend to hire just want a free casework. Although I still finished it I regret. After I sent my work I got reject from a no reply email lol. My own experience just added as another evidence….
