I applied through the flyer sent by one of the professors at my University. My first interview was scheduled at University. The interview was basically formal talk. They discussed my resume and background and touched base about what company is and what it does. I was told that they will let me know in two weeks however I was not contacted. I followed up after one month and asked about the interview result and then they scheduled my next round. This round was one on one with the one of the principals of the company. Again they touched basics of what company does and asked me about my background and future goals.
