The sector to start in is totally dependent on your interest. I would also like to know the stream of your MBA. If it's an MBA in HR, then there are many more chances of getting a job as a recruiter since you are a fresher. However, for freshers, they don't offer high salaries to fresher recruiters. So, if you could go into an HR generalist profile, it would definitely help you in enhancing your HR skills.
You can post your resumes on job portals like
Naukri.com,
monsterindia.com,
timesjobs.com, etc. You can also post your resume to consultancies, but I would suggest not to expect much from consultancies because firms hardly hire freshers from consultancy. However, consultancies can help you in getting jobs in the Hotel Management field.
All the best.
