Really a nice interview process i'd over there. Machine test with 1 hour duration would be given first. After onwards technical round would be there. There they're expecting very strong knowledge on basics of Objective-C. If you're well with basis knowledge and oops concept. And, they're expecting the people who can learn new techniques as soon as possible. Even, they're following latest techniques for designing patterns. If you're fit with this. Then, you'll be selected.

i have given online test and two technical round and finally hr also confirmed that i got selected.but i did not get offer letter, no response from HR after one weak.totally waste of 1 day.
