Sometimes I think I'm exaggerating because all he wants is money's worth. I should be working hard and giving good quality work. But once he explains and we agree to build features in some way, discussion on the same thing irritates him. Once I misunderstood what he wanted me to test. Next day he gets angry and mumbles for 5 minutes and then get's angry because he just wasted 5 minutes saying the same thing. Most of my work is good. There is a senior guy who is nice person. He's been there for 2 years now but last 3 guys hired in my place left within 3 months. One was fired, other two left.
