Pros
1. The benefits were not execrable. 2. Valuable learning experience. 3. I enjoyed the people I worked with. 4. They supported a healthy work-life balance.
Cons
HCL has a professed philosophy of EFCS (Employee First, Customer Second): keep your employees happy and they'll make the customer happy. Absurd budgeting mechanisms and rigid top-down management make it impossible to follow through on that admirable goal. There is no corporate "bench" to speak of, and managers are not allowed to make hiring and firing decisions. I was given two weeks' notice five days before my contract ended, and right in the middle of the holiday season, despite the fact that 3 teams had expressed interest in interviewing me. They implemented solutions always with an eye to increasing the customer's dependence on their services.
