The interview was held on campus for one hour. I was interviewed with two Indian people who were young and nice. They asked me something about my resume and then directly went to the technical section, which contained two questions.

The first was to write a tree class (it doesn't have to be a binary tree) and print out the level order of a tree.

The second one was about a file with three columns: name, size, and category. The task was to print out all the lines that mapped to a specific type.

The interviewers were nice and friendly. I think I spent too much time on the first question (though I got it correctly), so I was rejected after a week.

Print out the level order of a tree.
