Perguntas de entrevista de vagas de SAS Programmer da empresa Tech-Observer

They didn't tell me they just interviewed me for programmer until I was there because they posted their positions together and I was applying for biostatistician. The HR were very nice. But my interviewer was very rude. He let me waited for 30 mins after the time of our appointment and didn't say anything about that. He kept answering his calls during our interview. Never contacted me since the interview unlike what he said.
