Coforge QA Automation Engineer interview questions

It was a waste of time even though it was a telephonic round. The interviewer seemed to be a teacher of java, who was asking all those bookish questions, constructor chaining, for loop while loop, object creation. Then he asked me a question for printing a triangle pattern, for which i suggested using while loop, & he started arguing that why can't we use for loop, to which i said that the complexity would remain same with both the loops, we can use any. Then he asked me the time complexity of binary search, and i said O(log n), they he asked me to explain this. so i was explaining through a binary tree & he said that i had to explain the binary search & not the binary tree...:D . I am lucky that it was a telephonic round & I had refused for a F2F earlier. Then he started asking me that why did you not use TestNG for regression testing, to which i responded saying that i had created a data driven automation framework, for which i really didn't need unit testing framework like testng. And as expected he didn't look satisfied.... NIIT Technologies need to first hire a professional & skilled technical panel who don't ask questions using google.
