I applied through university. The process took 2 days. I interviewed at KBR in Jan 2008
Interview
The interview process was quite detailed. They invite you a day before and have a dinner with the managers, then the next day, you have a breakfast orientation and group discussion, the core interview (2 sessions) and lunch with group of people, and the final session of core interview. I found out that they evaluate ALL aspects. Not only during the core interview, but also all the group discussions, meals, etc.
I applied online. The process took 4 weeks. I interviewed at KBR (London, England) in May 2015
Interview
Long winded, and time consuming, slow in making a decision and many candidates in the running for the same position. Whilst I didn't get the position, the whole process didn't inspire me to join the company.
