The quality of engineering schools in Germany are quite uniform. However, there are some better-known ones, such as TU München, TU Berlin, RWTH Aachen for example.

You may also consider the Fachhochschule system, basically a University of Applied Sciences. They have a more hands-on approach than the usual universities. This is the best way for you to get real close to relevant industries when you graduate.

Another factor to consider is their cooperation with well-known players of the industry. The north is well-known for heavy industries such as maritime, while the south is automotive.

Fees are minimal, a ballpark figure of EUR100 per semester is expected. Your main financial hurdle is your living costs. Budget at least EUR1000 per month to live comfortably. As a student, you may work part-time but are limited to 90 days a year. Since you already have a bachelor's degree, I would suggest you to find student work in relevant areas of your expertise and not waste time in being a pizza delivery person or factory worker. There are many opportunities on offer in Germany.

You may contact DAAD for further info regarding applications, deadlines and other legal info.

I have studied in Germany for 4.5 years and is now working here since 2008. Therefore, my info may be slightly outdated.

UK isn't the same as Germany. Serious employers stick to the rule. I wouldn't wanna work with non-serious employers anyway. Furthermore, if anything happens on the job, the workplace insurance will not cover you. Furthermore, only low-skilled jobs will try to skirt around the rulings. If you plan to work for say an automotive manufacturer, trust me, they will stick to the rules.

They do hire students. It's called Werkstudent. You are basically hired while you still are studying. Of course, you get paid less, but you are there to learn. And the pay is not too bad. Degree holders still studying get about EUR12 per hour in most companies. So if you work say 12 hours per week, it's quite helpful. Monthly income below EUR450 is Sozialabgabefrei, so you get almost nett.

And please don't work as a pizza delivery guy or waiter. It's just a waste of time, low pay, and you learn nothing. Even universities hire students as lab assistants or research assistants. That way you can even get into the good books of the hiring professor.

Yeah, they are quite well known in the computer science field as well. As I said, the university standard is quite uniform. It is just up to you to be able to get admission and also survey a little on what industry players are working with the said universities. Look at what companies are well-known in your field, then look at where their main offices are, then look at what universities are situated in the region.

There are very few bachelor's degree studies conducted in English. Therefore, you must pass a certain German language proficiency test before allowed admission. You need to contact DAAD for the latest info.

For postgrad, there are more available in English. For these, I'd recommend taking at least A2 proficiency in Malaysia.

You most likely will not get a visa if you just plan to take a German language course without having at least admission to a university first. It is not that easy nowadays.
