I´ve read that a very common interview question is:
"What is 'turning you on' in chemistry at the moment?"
"I would be likely to say:"I like analytical Chemistry the best."
But I have almost no knowledge about this topic (just titration, nmr spectroscopy, mass spectroscopy, chromatography, x ray diffration, precipitation reactions,..) and if they ask me a few more in depth questions I probably can't answer them.
So, would you recommend me to prepare in a special field or isn't this essential?
