The interview process consisted of 7 rounds, out of which 2 were assignments and the remaining were face to face interviews, and a general discussion. The surprising fact about this interview is that the assignments were related directly to the company's customer facing artifacts. Generally, if a software engineer is interviewed no company exposes the code and asks them to fix bugs or test actual code (for a QA). However, my first assignment was an extensive review of one of their documents and provide review and improvement comments. The second assignment was to create a power point presentation to describe a complete plan and implementation of all improvements. They also asked me to include information on how the implementation could be done. So basically a complete brain drain and knowledge transfer during the interview process. There were interviews with the Product manager, Director of Product Management, CTO and CEO. Besides, there was a general discussion with the technical writing team.
Interviewing Advice: Please stop demanding work for free during interview process. A company that hires alone deserves the work of a candidate.
