Ireland

Well both the countries offers more or less the same schemes. 12 to 6 months in Ireland depending, if you hold a level 8 or 7 degree. If in Switzerland, you have 6 months to look for a job and you cannot extend the 6 months work permit.
I will favor Ireland because you may have allowed to extend your permit, if you obtain permission to remain in the country by pursuing further study, permission through another scheme or obtain a green card.
You should always check the immigration websites and contact them. The universities also have separate international student's offices, please check with them and make a comparative study.

Go for UK, Germany, Canada, USA or Australia for IT.

You need 6.5 bands in IELTS for a good college.

If you pursue MBA from the respective countries then you do have a good chance to seek employment. A good career is dependent on many other factors apart from seeking an MBA.
However, if you have done MBA in general management from India then job opportunities in USA/Ireland would be bleak for you.

Hello Avdhesh,
Ireland is one of the study destinations chosen by most of the students.
Here is the list of top colleges/universities in Ireland:
1) Trinity College Dublin
2) University College Dublin
3) National University of Ireland, Galway
4) University College Cork
5) Dublin City University
All the best!

You should opt for the UK. There are a lot of disadvantages when we compare the UK with Ireland as Ireland is a small country and it is very hard to get a part-time job even in Dublin. The reputed universities are mainly located in the UK. Another fact we can consider is that European headquarters of Google, Facebook, Apple, Intel, Dell, AOL, Paypal, Microsoft, and eBay are in Ireland.

63% is not a good score. You need to crack GATE, GRE and TOEFL exam with top AIR ranks.

Canada and UK could be better options. There is a demand of management engineers in these countries. Check Canadian Society for Engineering Management and Engineering Council UK for job prospects and more information.

Yes it is partly true as most employers prefer employing those people who have work experience of at least one year. This may not be the case for international students, so finding a job in Ireland could be hard.
