Hi,
Welcome to PG.
There is nothing like an ideal work-ex kinda thing. U must be able to justify ur decisions n choices at the end of the day.
Go through the below link to get more threads relevent to ur query:
Career Discussions - PaGaLGuY.com - The Everything of MBA, CAT 2008, GMAT, XAT, IIM
Do search for the info. before starting a new thread. Also, for personal discussions, starting a new thread is not encouraged at PG.
Introspect urself, ur needs, constraints & n limits before goining for any decision.
Personally, i feel that work-ex helps in MBA n for abroad, generally 2 yrs. of work-ex is needed.
Hope this helps.
All the Best!!!
