I was contacted by the HR through an email to let me know that I was going to have a interview. I feel the HR person very professional, as he/she ws making sure that the contact information they had was accurate. They contacted me in less than a week after I submitted the application, and for my first interview it took at least one or two more weeks. Although, I did not get the job, the technical interview was a great experience for me , the person I spoke to was very nice. While he has a very good background, he made me feel comfortable speaking to him. He was also fine to answer questions regarding the company. Overall it was a great experience which says a lot about the company.
