Infosys Associate Developer interview questions

I was told to take an IQ test beforehand then I had a Skype interview with two developers. The interviewers mostly asked me technical questions, such as how to make a for loop, or how to access an array. I was also asked a couple behavioral questions and "If you were a tree, what kind of tree would you be?" Honestly, these interviewers seemed easily annoyed when interviewing and one of them started cutting me off as I was answering. I hated getting asked what kind of tree I would be. How the does that relate to the job?
