When it comes to picking a career it’s difficult. It does not matter how old or young you are. We go through different questions. What do I want to be when I grow up? What subject will I pick in school?What will I do in college? What will I do after college?
Lucky for us times have changed and we do not have to pick one career for the rest of our lives. Changing jobs is part of life now if you’re not happy with your job just get a new one. Job hopping is normal. But does it look good on a CV? The answer is Yes and No; different jobs can show experience. Having too many jobs over a short space of time is never a good idea. It looks like you cannot stick at something and the employer does not wait to hire you, train you in and you leave.
So, what are a reasonable time to stay in a job to get the full experience from this position and enough time to know the job is not for you but still looks like you gave it all you could?
On a CV, anything less than a year (if it is not seasonal dependent) looks bad. The best advice I can give you is stick with it till you find a new job.
