Applied on LinkedIn. The HR contacted me and scheduled a telephone interview with the director. But the director didn't call me and neither the director nor the HR informed me. I emailed the HR but he never replied. I got in touch with the director himself on LinkedIn. He apologized and said the time zones mixed up since they had offices in US and UK, and they had many projects all over the world. He rescheduled an interview with me. The 30-minute interview was all about technical questions, such as how to calculate the sample size, how to do power estimation, etc. Then he asked me to email him back in Feb 2014 (because I couldn't start working until May). I did so, but never heard from him again!
