Before phone interview I was asked to complete a online task in Linux. Then they scheduled the phone interview. It truly is the worst phone interview I have experienced ever. The man who interviewed me was rush, mean and rude. Obviously all he wants is to get this interview over with and he did not give a damn about how the interviewee is doing.

it took about 2 weeks. First step is to build their application gt.m where unix/linux concepts are tested. Then theres a technical round of interview. questions were on databases, data structure and algorithms(trees and hash table), computer architecture, problem solving questions, linux/unix questions
