Applied through the company website and after 2 weeks HR called asking some questions and then HR sent the interview details and case study through email. The case study is related to the position and thus was required to be done. A week later was the interview or more accurately a technical assessment with some interview sprinkled in. Questions on planning, error finding and software engineering were asked. It was tough, especially more so when my preparations were inadequate. The interviewer gave hints to try and help me with the puzzles several times but I was still unable to get the correct answers. All in all, it was a positive learning experience.
