19 problems the CodeKairo catalogue tags as commonly asked in Indeed's coding rounds — 6 easy, 8 medium and 5 hard — each judged by hidden tests in 13 languages. The most common topics among them are Arrays (15), Hash Table (7) and Strings (5). Tagged for Indeed and no other company: Summary Ranges and Longest Common Subsequence. The tag is the catalogue's own annotation of where a problem tends to come up — not a list published by Indeed, which CodeKairo is not affiliated with.
