Which is a better course to pursue among event management, product designing and interior designing?

Hello Hamthok, Please refer to the following links: https://www.shiksha.com/hospitality-travel/event-management/articles/your-career-after-doing-event-management-blogId-4625, https://www.shiksha.com/careers/industrial-designer-63 and https://www.shiksha.com/careers/industrial-designer-636

All are good ones. However what is it that you want to do? Career prospects in interior design are better than the others. But if you can make through, event manager is quite fruitful too.

All are different from each other. But, if you are confused, then get all the detail of these streams on paper and, then compare. You will get your answer.
