Everybody have one or more hobby but the hobby you choose at a moment depends on the type of interview you want to attend.
For example,if you are to attend an interview in a financial institution like bank and the interviewer ask you question like; What is your hobby.
As an interviewee dont mention things like_ singing and dancing_. The interviewer will conclude that you will be spending much of your time in the club with hangover of alcohol and indian hemp and that will never profit the company and you will lose the job
Dont mention eating, sleeping as your hobby in an interview in banking sector, the interviewer will conclude that you are a gluttonious in nature and will be coming to work everyday late.
_**The interviewer will like to here things like;meeting new people, reading, writing, traveling and among others
