if you always dreamed of working in a staffing agency that's shrinking...
Pros
honestly, i can't think of many pros. if you are being recruited in silicon valley, be careful. read the reviews and figure out which ones are written by employees, and which ones are written by recruiters. and if you just want a place to bide your time while looking for a job, then take their offer!
Cons
trianz is a place to go when you have no other options. go ahead and interview with them, and ask them what percent of the people that were there 1 year ago are still there today. then ask them what percent of the people that were there 2 years ago are still there. get the picture? oh, and none of the promises made to you when you're hired will be honored. the company and its leaders are perpetually late, lazy, dishonest, uninspiring, short-sighted, cheap, reactive...not much else to say. there you have it.
