Just sharing experiences ... here in Saudi I deal with all sorts. Lessons learned
1. hire 1 Mallu, and soon enough his whole village will be there.
2. Mallu definition of teamwork is inter Mallu communication.
3. When applicant from Hyderabad or Bihar,double check certificates and divide the CV / 10
4. If applicant is from Hyderabad or Bihar or UP, divide efficiency / 10
5. In a team of 10 (hyderabadis + Bihari + Delhi + UP) just one of them will actually work, rest 9 are useless slackers and liars who piggy back the one working.
6. Indians are incapable of giving a straight true answer, they will always try dodge rather than to tackle.
These are real life lessons, learned in real life industry.
