Phone screen, followed by a Skype call or onsite interview. First, there will be a phone screen, and that person will decide whether you are worth interviewing further. Then, they will either call you onsite if you are near their location or conduct a Skype interview. I had one phone screen, followed by three one-on-one Skype calls, and then they flew me over for three face-to-face technical interviews.

Phone screen was basic networking questions, programming questions on C and Python, and resume.

Skype/onsite is purely resume, networking, algo, and DS (basic linked list, tree questions).
