Access
Preview honestly. Unlock when it is useful.
Starter includes a real question preview. Pro and Elite unlock the complete company-specific pattern sheet and full practice depth.
What is inside a company kit?
Each kit is a company-specific DSA sheet grouped by core pattern, with difficulty and time-scope controls, progress, bookmarks, editorials, and code destinations preserved.
Is the pattern signal company-specific?
Yes. Pattern and difficulty distributions are computed only from questions mapped to the selected company and active scope.
Can I prepare on a short timeline?
Where source data supports it, switch to the 15-day scope for a compressed, high-signal question set.
How does access work?
Starter users can inspect a limited preview. Pro and Elite unlock the full company sheet and its complete pattern coverage.
What a company wise kit is
A company wise kit is the set of interview questions Thita.ai holds evidence for at one company, grouped by the pattern that solves them rather than listed in the order someone happened to report them. Thita.ai holds interview data for 160 companies and ships a kit for 111 of them, across data structures and algorithms, low-level design and system design.
Why a pattern distribution beats a question list
Company question lists decay. A specific question that leaked last hiring season is unlikely to be reused, and preparing against the list rewards recall over reasoning — which is the opposite of what the interview measures. What holds across seasons is the distribution: which of the 16 pattern families and 100 subpatterns a company's questions keep landing in, and how much of its loop is design rather than algorithms. Each kit is built to answer that, and every question inside it is a working problem with an editorial, an in-browser editor in 6 languages, and an AI mock interview on the same pattern.
How to use a kit before an interview
Open the kit for your target company, read the distribution first, and pick the two or three pattern families it leans on hardest. Work those on the DSA Patterns Sheet until the setup is automatic, then come back and use the company's own questions as a check. If the loop includes a design round, do the same on the low-level and system design sheets. A week of the right three patterns beats a month of a two-hundred question list.
