I had applied online on their careers page. The very next day one of their team leaders contacted me to schedule an phone interview. The interview went on for 25 mins wherein I was grilled about the projects that I had put down on my resume. They explained me about the position and what would be expected out of an intern. The interview went quite well and I was told that my resume would be forwarded to the next person who would take the next round of the phone interview. After a week, one fine day - I got a call from their manager who asked me mainly about my work ex and the courses that I have taken relevant to the job. It was an impromptu interview and lasted for about 30 mins. I was told that if selected, I will be contacted within a week. And so did they! :)
