Perguntas de entrevista da empresa Digital Aptech

They called me in for an interview and said I got selected and then asked me to come for another interview to which they said I got selected again. Then they called to ask me for my salary expectations and said they will call back. When I called them back they did not pick up my calls and did not reply to my texts and blocked me on WhatsApp. Highly unethical and unprofessional behaviour from a company this established.
