Start with non-negotiables: age, educational qualifications, and medical standards. Then compare work locations, promotion paths, and bond periods if mentioned in official PDFs.
Speak with people in similar roles when possible—online forums help but vary in reliability. Prefer official FAQs and previous year notices for ambiguous clauses.
Once you commit, align your study plan to that exam’s pattern rather than chasing every overlapping test. Depth usually beats scattered attempts.
