Come on guys, dont you think you are being a bit harsh.
Yes there was a one sentence question but then a whole bunch more about differing standards.
Perhaps the original poster knows more than he has posted, perhaps not. But sniping at every comment wont achieve anything.
Do I trust engineers? depends on the individual.
Nothing to do with authorities or nationalities or anything else.
I would hope though that the company employing the engineer has done their homework on him.
As to differing standards, many misconceptions often arise due to a lack of understanding of the local language and culture.
If there really is an issue out there it should be dealt with. However at the moment no evidence has been posted here.
