Each company (especially in the Information Technology sector) has its own set of technologies, skill sets, and concepts on which they test the candidates to know how well they will be able to perform in the company. Thus, they use Placement Tests (among other hiring criteria) to check skill levels of candidates.
In India, the placement session for any IT company generally has 3 – 4 rounds: The first round is the written test, consisting of Quantitative aptitude, Reasoning (logical ability), Verbal ability (English) , and computer science subjects (C, C++, Data Structures, Algorithms, DBMS, OS, Networks, etc.). Some companies have a coding round, which is sometimes taken as a separate round and sometimes is clubbed with the written test. Subsequent rounds are interview rounds, the first two usually being the technical round and successive rounds being the HR round.
The Placements Round 1 (Written Test) will cover the following :
1. Quantitative Aptitude Numbers LCM and HCF ( Learn | Practice LCM | Practice HCF ) Work and Wages Pipes and Cisterns Time Speed Distance Trains, Boats and Streams Percentages Ratio Proportion and Partnership Mixtures and Alligation Algebra Average Age Profit and Loss Simple Interest Compound Interest Mensuration 2D Mensuration 3D Trigonometry & Height and Distances Progressions Logarithms Permutation and Combination Probability Geometry Clocks Calendars Coding-Decoding Race Simplification and Approximation

Some essential tips to prepare for these placement tests are:
Solve previous year exam questions and mock sample questions as final revision. Read interview experiences of previous year candidates to get a better idea of hiring. If possible, read or talk to employees working in the same company. (Use website like Glassdoor) Practice Mock Interviews, to identify area of weaknesses.
