Pros
Exposure to more variety of technical problems than you could possibly imagine
Cons
You are essentially responsible for finding your own internal work. You will only be fed for so long. After that grace period you will be scrutinzed weekly and your UT evaluated. Typical targte is 80+% but given that vacation and sick count against you, by working 40h week at 100% the maximum UT you can achieve is 90%. What does this tell you about work life balance? Expect the tiniest infractions to be blown out of all proportion at review time. Do not expect to be told what is really required of you to advance - they will not be upfront about. Senior staf are expected to bring in $150+k of business, promotion to manager requires $500+k, senior manager $750k-1M and Principal $1M.
