You have reasonable concerns. Take a look at this post: How to use LinkedIn to find the best school www.find-mba.com/board/33571

I suggest you look at the careers of people who have graduated from that school, perhaps focusing on those who have come from your country or from engineering. If their careers interest you, and you have a similar background, then perhaps it's a good idea.

Of course not every job requires an MBA but every large firm employs MBAs. The MBA is a degree in business administration so, if you don't want to be that sort of manager, perhaps a specialised masters degree in engineering management or power might be better than an MBA?

Also, it depends on a lot of different things. Is the school in a country where you can speak the language at a professional level? If not, your post MBA options will be somewhat limited in that country. If you only speak English, perhaps a business school in England would be your best bet, but make sure you understand how the visa process works. It's not as straightforward as it might be in other countries.

Indeed, most jobs will not *require* an MBA. But people get an MBA not to meet minimum standards but to give themselves leverage to get better jobs and make more money. You'll find that most of the triple-accredited business schools have solid connections with a certain set of employers, who will reliably hire MBAs from that school.

As the user above noted, look at those recruiters and who they hired and for what position, and see if those kinds of jobs match with your career goals.
