Applied online. Received a call for two back-to-back interviews. The interviews weren't too hard. The corresponders were extremely polite and accommodating. However, I guess they look for a very clear understanding of concepts on every topic.

A first HR interview that explains the desired needs and allows assessment of whether one meets the search criteria. A second technical interview with a professional that verifies one's ability to work for them.

Applied online, completed an online test, and went through a couple of phone interviews. The onsite interview involved four engineers and a systems design component. The interview was really tough; I had to postpone it a couple of times to prepare.
