28 problems the CodeKairo catalogue tags as commonly asked in Accenture's coding rounds — 25 easy and 3 medium, no hard ones — each judged by hidden tests in 13 languages. The most common topics among them are Arrays (18), Strings (7) and Math (6). CodeKairo's Accenture — Cognitive & Technical mock covers the Accenture Cognitive and Technical Assessment pattern, which runs on a single clock and so rewards a different approach from most placement papers. The tag is the catalogue's own annotation of where a problem tends to come up — not a list published by Accenture, which CodeKairo is not affiliated with.
