1.Most of them are 1 year program as you know...so,should one consider these for career change (re: Industry change not job function change)?
A one year program can be very effective for a career change actually, especially if your background and skills are alread a good preparation for your move. While the one year program does not provide the kind of deep coursework to choose a ton of electives, if you have the right background for an industry change, the one year can clearly get you on the road more quickly without as much expense.
2.Could you please let me know like INSEAD & IE whether LBS,Said & Judge also have rolling admissions and two intakes (for example, one in September 2014 and other in January 2015 for INSEAD)...?
This is not really a deep insight kind of question, but can be ascertained by a fairly quick research into these specific programs. As you do your due dilligence on these schools, I am sure this question can be easily found.
3. LBS,INSEAD are top ones but in global b-school rankings (FT) b-schools like IE,Said & Judge are placed ahead of many top 20 US schools like Ross,Darden,Anderson (for IE only),McCombs...How do you see that for an International applicant & career changer?
If your plan is to work in the geographic region of those schools, it would be preferrable to go there. You will have your network close by which can yield benefits for a career changer. If you goal is to work in the US, I would look at Emory's one year program or Kellogg or Cornell.
4..For these European schools, is it always better to apply in R1 (if some of them don't have rolling admissions and/or two intakes) rather than in R2 like US schools...? Round one and round 2 should be fairly balanced for intake, but we generally recommend round 1 if you can have everything ready.
