There are many exciting jobs opportunities for hotel management graduates with the increasing competition in the hotel industry. Since a hotel has many departments such as Operations, Front Office, Food and Beverages, Accounting, Sales and Marketing, Engineering/ Maintenance, Security etc. one can opt for a field of their liking and pursue a career and successfully grow in it.
Apart from jobs in Hotels and restaurants, hotel management Diploma holders /graduates can find good jobs in:
Airline Catering (flight kitchen) and Cabin Services
Club management
Cruise Ship Hotel Management
Hospital administration and catering
Hotel and Tourism Associations (for eg: state tourism development corporations)
Hospitality services in the Indian Navy
Hospitality services in various Mncs
Forest Lodges
Guest Houses, resorts
Kitchen Management (in hotels or running canteens in college, schools, in factories, company guest houses etc.)
Catering departments of railways, banks, armed forces, shipping companies etc.
Hotel and catering institutes (as a management trainee/ marketing or sales executive)
Self employment (as an entrepreneur)
You can also apply for PG courses in Hotel Management which will lead to even more exciting opportunities. Good Luck!

I would suggest, don't decide on any AI area until now. You have so many years ahead of you. So welcome all AI topics. Learn, exercise and explore everything you find interesting. After 3 or 4 years (until final year at college) you might find your heart racing for one domain more than others. After that you should decide your field. Do your final year's project on that. Make sure you choose your dream project pretty challenging and start 6 months ahead of what your college prescribes/advices for final year projects.
First be strong in your logic. Which means you should have more than 1 or 2 tool (s) to solve your problem. By tools here I meant mathematics. Concentrate on Linear Algebra and Calculus. One of my professors used to say "Anything and everything is linear algebra. Give me any problem in any domain, I will use LA to solve it". Mind that he is a multi-disciplinary professor and he means it.Statistics, probability theory and graphical models - These are the fundamentals for modeling your problem and doing inference from models. So now you have got tools to solve them, but how will you express them to the computer/machine? Be strong in any 1 language, preferably C+ or Java. Python is a boon if you can learn it. Then to advance further, learn some functional programming languages to scale in distributed environments. See linear and functional programming/quadratic programming series from Coursera.
Intake up /prepare for competitive programming like ICPC, google summer of code, etc. More problems you are exposed to better will your analytic and logical skills get (I never did this in spite of having a fetish for programming, I regret this a lot). It's time you start doing some MOOCs. For any AI task ML is important. So do 3 courses from different professors. The reason is that each one will have a unique new approach towards teaching ML. Learn all flavors of ML then move on to narrowing down where you want to apply your ML and do further study/course on the narrowed down field, maybe NLP, speech, vision, robotics, etc. Choose top journals from your area of interest and keep reading papers from them regularly. This way you can keep track of where the area is marching and state of arts.
