Preguntas de entrevista para el puesto de Principal Engineer en Infinera

I applied for the position at Bangalore location. The HR asked me to come for a face-2-face. I requested him for a telephone round with the hiring manager to understand the requirements mutually to sort out any incompatibilities earlier , as it is a senior position. The telephone interview was scheduled , but some other manager ( not the hiring team's ) speaks to you over phone...I told him clearly what my experience is , what might and might not suit them etc and requested him to clearly convey the same to the concerned hiring manager before deciding to call me for a f-2-f. But it never happened, they called me for a f-2-f, then asked me if I have the skills that I have told over phone that I don't have, then HR comes to you and says "Sorry..it is not positive..". Wasting time on both sides due to lack of coordination or lack of seriousness..
