Dear Candidate,

For joining you need to give, HCL SAT. It consists of two phases:-

1.HCL SAT Online Test

In this, you will undergo a basic online test consisting of quantitative, logical reasoning and language abilities.

2. Interview & Counselling

Undergo a face-to-face interaction with HCL selection committee to prove your mettle.

It's good to have knowledge of class 11 and 12 but this test is a basic test designed to test the quantitative logical and language abilities of a candidate. So I think you need not to have a deep understanding of physics chemistry mathematics as you will be working as a software engineer or a database guy so focus on quantitative and logical abilities.

All the Best, CHeers!!!
