Hi,
Over 3 years of work experience is a good one and coupled with BE background, you should definitely have bright chances. If you are unhappy with the current work profile that you have, ask your concerned manager if there is an option to change your profile- something that is a win to both of you. If not digital marketing, any other area of specialisation that will interest and challenge you as well as is a need of the hour for the company. If there are none and you are very unhappy with the profile and want to mandatorily choose digital marketing, then start applying for jobs on leading websites and request for references through friends in the digital marketing field. Sooner the better. Of course, since you won't quit working until you land another job, it should not hurt your finances.
Wish you all the best.

Hi,
1. Work experience - Nothing can match this. Choose a job role that suits you or at least interests you remotely and get practical exposure working in an organisation. It also gives you time to reflect in the mean time as to how to proceed going forward. When you are working, lot depends on how innovative, creative, disciplined and forth coming you are as an individual. Take up more responsibilities and work, build your contacts slowly and steadily, be on the look for resources to boost your knowledge and skills internally or through online support. Initial years of work experience should be full of learning and stretching yourself.
2. Higher studies - There are people who prefer Masters in similar subjects or related ones as in graduation and others who want to make a shift to Management zone like an MBA. My suggestion, wait for 2-3 years to make this move. See, when you want to take up the Masters. Say 2 years after working, then you must get going after 1 year into working as it needs lot of preparation. But if its like an MBA or even a technical course which itself needs minimum of 3 years work experience then take that much time. Only advice is, research a lot as to which universities and courses you want to do and speak to the alumni from the place to see if your understanding is on the same page.

Firstly, I would suggest you to take up work post the BE course. This gives you proper hands-on corporate exposure with whatever you have studied. As far as the distance courses are concerned, be sure to check the reason why you would want a distance course. Is there any reason, like to enhance your practical or specialised skills in mechanical field for job prospects? Or is it altogether a shift, like a distance MBA? If anyway you are ready for further studies, my suggestion would be to get a couple of years of real-life professional experience. Figure out things and then make a move.
For Masters, countries like Germany hold a great path ahead and if it's MBA, then yes, 1-year or distance or even distance + classroom modes are available.
