Two months after the job application (!) an interviewer from one of their overseas offices phoned my mobile number 5 times in a row. Due to the unknown nature of the call and the fact that it was an overseas number, I received an email shortly after to be invited for an interview. A separate interviewer I spoke too during the actual interview was late as well, and after a whole hour of conversation, simply ghosted and never proceeded with any updates on the interview process.
