Technical test (written)

Technical written test is quite different from the “Aptitude Test” which is commonly called as “Written test”. While in Aptitude Test questions asked are general in nature (Verbal, Quantitative & Logical) and is common to all candidates, recruiters (mostly IT companies) sets this round to test the knowledge on specific domains, such as C, C++, Java, ASP, SQL, Networking etc. The questions sets also differs from branch to branch and is mostly for engineering students.

As the pattern varies from recruiter to recruiter and also from branch to branch, it is not possible to give you an universal test pattern. However just to give you an idea, about 30 questions are asked, which you need to answer in about an hour.
