FDM Group Software Engineer interview questions

Quick interview. Very easy questions. After being told I was in the program and not given a contract, the hiring manager cut all contact. The Singapore recruiter would not reply to any emails at all regarding start dates/pay specifics. Did not answer direct calls, until I called the company and someone sitting next to the recruiter picked up and handed her the phone. She told me she would not be able to answer my questions and will call upper management and then ring me back. I never received any communication back until weeks later when she emailed asking if she could call the next day. I said ok. She never called the next day... A week later I get another email asking when I could be called, I replied but again never got a call. Very unprofessional hiring process.
