The phrase 'career objectives' means more than just 'what job do you want' - it means 'what are your plans and hopes for your career'. You could perhaps express it like this: 'what job do you want to have in 5 years' time?'
It's not good English to say "I want to try my best in anywhere". You could say "I always try my best in whatever situation I am in" - this would be a good thing
