AAI Junior Executive (Air Traffic Control) selection starts with an online computer-based test covering English, reasoning, maths, physics and general knowledge.
Shortlisted candidates go through a voice test, where pronunciation and fluency are checked, since ATC work is communication-heavy.
Document verification and medical examination, including vision and hearing standards, come next.
The final merit is based on the online test marks, so check the official AAI notification for the scheme and cut-offs.
