Hello Sameer. Planning masters in Germany is a good option and when it comes to Mechanical Engineering, then it can prove to be one of the best decision. The eligibility criteria for MS in mechanical engineering in Germany is having a B.Tech/B.E degree in Automobile/Mechanical Engineering from a recognised university. You need to have minimum 1-2 years experience in the same field so that your chances of acceptance gets higher. Also, I would like to tell you that IELTS/TOEFL score is required to prove your english proficiency. You need not write any other exam to pursue MS in Germany. I hope you found this answer helpful. Good luck.
