SSC CGL recruitment uses a computer-based examination structure. The exact papers, modules, qualifying requirements and merit calculation must be taken from the notice for the applicable examination year.

Do not use an old Tier-II pattern without checking the current notice. The papers required for a particular post, qualifying modules and final merit rules depend on the official scheme.
Is there an interview?
The modern SSC CGL selection process does not generally include a conventional personal interview for the CBI Sub-Inspector post. Final selection and allocation depend on the applicable examination rules, merit, preferences, vacancies and required verification.
