Which dept? Different depts would have different job descriptions for Technical Support Engineer. Usually, you provide and handle day-to-day technical requests/enquiries from sales engineers (as far as I know)...

Working environment... Ok-lah, not too bad, some depts would have quite a bit of interaction with other ABB offices abroad. Depending on which dept too, might have rather long working hours. A lot of hierarchy and politics and bureaucracy in the company, but oh well, I reckon it's the same case for lots of other companies too.

I could be wrong/inaccurate, so you could ask around

You're in Robotics? Not too sure about that dept though, wasn't there long enough to find out

No longer working there, today was my last day...
