On 1st day of Interview after all Round HR told me you are selected in WISSEN, will update you(Gave 3 round of interview). 2, I got all from another HR after two weeks, one more final round interview in Pending, i gave final round interview in November. 3. After 1 week i got call from same HR mentioning one more final round interview is there with onsite person. i completed that also. 4. Again in December HR told me now will have client round and every time they are telling this week interview will happen and today till 16th January interview did not happen. They are not even sure how many round interview process they have. as per them your time is not important.
