Entrevista
Most questions were related to Android platform and not app development per say. The interviewer himself was talking for most part. The worst thing was the HR didn't bother to get back to me after the interview. They didn't reply to my email.

Highly Unprofessional HR and process. They call you so many times to fix interviews but cant call back once to inform you the feedback, Has happened 2-3 times. I mean how difficult is it to convey the feedback?
