Pros
It's a good consultation firm as compared to others running in Canada. You work with and report to client and Synechron collects your feedback from the client without bothering you.
Cons
If you are working on a project, then it's good. Otherwise, in Canada, Synechron only has two accounts - Citi in Ontario and Morgan Stanley in Quebec. They do not have any internal projects of their own to keep you on payroll. If you are rolled off from your client project, they keep you on bench for 4 weeks and during that time, they generally fail to allocate you to other projects as Synechron does not have sufficient projects in Canada. Post those 4 weeks, you'll be terminated with no fault of your own but because Synechron does not have projects for you.
