READ TO THE END!!!
This was the most intensive interview I have ever attended. It was 2 hours of short tests typing as fast as I could answering standard interview questions followed by tests to prove basic competency on a laptop. They also had a toned logic test that is near impossible to pass. They then take you straight top the oral interview.
They expect you to not be able to finish everything. They are testing to see how you cope with stress and a time crunch. It was the most productive interview I have ever attended and I intend to form my future interviewing techniques based on their methods.
