Pros
Timely salary - last working day of the month If you are on bench, HR will proactively look and get you assigned to a project. The process at HCL will make you go through Job Based Certifications and courses, which is good and will help you.
Cons
Does not follow its own tag line "Employee first", its more like client first or money first. The appraisal cycle can get delayed for months. Low paying company according to its competitors. Many process related things are really slow at HCL. You will see many many post from employees other than HCL giving gifts, bonus and bounties but you will hardly or never see that from HCL in India. Officially gives 3 months notice period while does not accept more than 2 months notice period while hiring. Very small increments.
