First, you have to do a Hirevue interview. If you are selected for the next round, which was my case, they schedule an interview on site. The people that interviewed me were really nice; all the questions were behavioral questions.
Interview questions [1]
Question 1
Tell me about a time you failed, and how you handle it.
Fairly simple process in whole, CV application as usual, followed by some tests online, standard pattern recognition, numerical verbal reasoning, then an interview with a case stud, practice that and you should be fine. Process was pretty standard otherwise.
I applied online. The process took 4 weeks. I interviewed at Phillips 66 (Bartlesville, OK) in Jan 2016
Interview
All of the questions were behavioral questions requiring a STAR format response. The interview was relaxed. I had three rounds of interviews for 3 different positions. Each interview was 30 minutes long and was a panel interview with 2-3 people.
