Very bureaucratic, "check box" culture which is also very hierarchical.
HR department has been replaced by a computer, but this is also true of many companies.
Treats staff like commodities that can be shipped around the world to work on projects without suitable experience or skills. Burns them out and replaces them.
No investment in people, equipment or ventures unless a client is paying for it.
An example of mandatory company training consists of a webex at 5 am with a presentation from someone in India reading a badly written script. Be prepared to pay for you own training if you need to learn new skills.
Has pretensions to be being a global company, but really it is an Indian company with a few satellite offices. Difficult for Europeans to prosper since they just don't fit into the culture and won't be given senior positions.
Don't be fooled by the UK Top Employers Institution badge: It's a subscription, not an award.
If you are based on a client site (many UK employees are), you will be forgotten about. In these scenarios HCL is like a contracting agency and will email you daily to complete your timesheet so that they can charge the client for your time and that is all the interaction you will get.
HCL constantly spams it own staff with campaigns, silly competitions, mandatory check-boxing, and invitations to presentations or evening events that are in Bangalore or Noida - another example of not filtering content or modifying the company culture for European staff.
Integrity is in short supply. Peter's principle isn't.
