Only you can answer this question as you know how willing you are to work hard. MS is not the easiest course, it requires a lot of hard work, sacrifices and knowledge to pass the course.

That totally depends on you and your skills. If you are great at your studies and professional practice then no one can deny you a job you deserve. No one can guarantee you jobs or predict the outcome after you finish your course. So this question doesn't have any right answer to it. It will all depend on your situation and efforts.
