I think Hitachi hire consultancy only for the interview scheduled and another consultancy for interview.
They have taken first round and got selected.
But for second round they never get the panel i don't know who is wrong here.
One day i got to know opening is closed.....what's this......if you don't have opening why wasted time to take interview and if you need quick joiner do the process fast.
Hitachi you are very big organization please take care about your name
