The interview consists of a lot of technical questions about 15c3-1 and 15c3-3 rules. It was two rounds with examination directors. I recommend studying on the rules and be prepared to a writing exam. They want someone with proper grasp of the English language.

Recruited at a job fair for an interview as a graduate student. Interview was not difficult, generally behavioral questions and an assessment of the role for which you were being interviewed. Never heard back after follow-up with recruitment team.
