I did an initial chat about my background, then was asked to do an over-the-phone live coding session. They were very prompt on their phone calls, calling almost exactly on the hour.

A phone call interview first than coding exercise. At the very beginning, the HR set a time for a phone-call interview to talk about my experience in software development and any related information. As a international student, he asked if I need or not sponsorship. They will not provide sponsorship for entry level developer position. Then we set a time for coding exercise, which is an online, paired programming exercise. HR describe a problem, you will try so solve the problem use whatever languages you like.
