4How is this different from what I learnt in college?

The course that you studied in college was designed years ago and does not take into account the current market trends or what the industry expects from graduates. Our courses have been designed in consultation with industry experts and leading academicians. Skill-Lync courses are geared to help you find employment as soon as you complete the coursework. This is possible only because of the projects that you will complete as part of your curriculum, in your college you might have done one major and one minor project. But, each module in a Skill-Lync course has a corresponding project, and these projects are industry-oriented. Which means that if you were to look at the project that an engineer at a top OEM is working on, it will be similar to a Skill-Lync project, the only difference being the scale of the project. 


Simply put - there's a world of a difference between what you have studied at your college and what you will get trained in when you study at Skill-Lync. 

5What advantages will I gain by taking this course?

You will have an edge over your peers by working extensively on industry-relevant projects, practice on tools and software that will set you apart and help you in getting ahead of the competition.

They will help you polish your resume, and help you properly present your projects on your LinkedIn and other external pages. They will also scour for any opportunity that you might be qualified for and help you apply for it. After which they will train you in all the possible variations of interview questions. The Student Success Team will also train you in tool tests, in which your comprehension of all the tools that you have studied in the duration of the course will be cemented along with the underlying principles.

6What is Body in White (BIW)?
