40 problems the CodeKairo catalogue tags as commonly asked in Wipro's coding rounds — 36 easy and 4 medium, no hard ones — each judged by hidden tests in 13 languages. The most common topics among them are Arrays (22), Strings (13) and Math (12). CodeKairo's Wipro NLTH — Aptitude mock covers the aptitude block of Wipro's National Level Talent Hunt (NLTH), the quickest services paper in this catalogue at under a minute a question. The tag is the catalogue's own annotation of where a problem tends to come up — not a list published by Wipro, which CodeKairo is not affiliated with.
