Vois (India) interview questions

It took almost 4 months to complete the process. after applying to position i got call from HR almost after one and half month. close to 2nd month 1st round got completed. again there was a gap over one month to get 3 round schedule. 3-4-5 round was done by SO. they gave me case study in each round almost 1 hr of discussion. Post completion of 6 final managerial discussion round HR comes back & inform "SORRY THE POSITION IS ON HOLD" VERY VERY VERY FRUSTRATING. I send over 4 months in this process. HR POC's doesn't reply.
