I cleared the written round After that went for face to face the person who took the interview was not known to my domain area. Actually he was substitute of some other person who was suppose to take my interview . After the interview they said We will mail you the result but they never sent any mail. I called them after a month than they said in that week no was selected. Its fine some can select and reject you . But its responsibility of employer to let the interviwee to be known with their result.
