Switzerland

You can get scholarships, provided you meet the criteria. You need to score more than 85% marks in academics and you also need to crack IELTS exam.

The answer will depend mostly on your qualification and skill shortages. Opportunities would be coming your way and you need to grab them. Network well and perform well in class. Every university has a placement office providing job information, you need to keep yourself updated with them. You can work part time while studying and after graduation, you will be allowed to remain in the country for 6 months while on the job hunt. On getting a job, work visa will be granted.

Dear Saravana,
ETH Zurich (Swiss Federal Institute of Technology) is Switzerland's top-ranked university and is highly competitive. Other well-known names include University of Zurich, University of Geneva, Ecole Polytechnique Fdrale de Lausanne (EPFL), University of Bern, University of Lausanne, University of Basel and University of St Gallen (HSG).

Engineering management is the need for industry. Engineering graduates need the skills to get work done by skilled workers. You become more employable.

It depends on the level of university and the course, which you choose. There is no age limit to pursue a course, but it is definitely a criteria for embassy while deciding to give you visa or not. For Master's course, the maximum age as per my experience is 35 and for Bachelor's, it's 24. Beyond this, you should apply for Ph.D. IELTS is not a country requirement as it's not an English speaking country, but certain universities will ask for 5.5 to 6.5 band for courses taught in English.

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.
