Perguntas de entrevista da empresa OPS

Very irregular process. They wrote to me saying they were going to send the interview questions 24 hours before the scheduled interview, but they failed. They only sent the questions 15 minutes before. That wasn't even the issue. After a few weeks, they requested that my referees provide references, and later made a verbal offer that I accepted. That was it. No further communication. I made several efforts (calls, emails, text messages) to reach them to no avail. Very very very very (how many very's) unprofessional and terrible lots.
