there is to it

#
這段話我一直看不太懂,特別是那個"there is to it"

"So, we've looked at various aspects of staff selection this term and I think by now you should all be beginning to see how much more there is to it than just putting applicants through a short interview or asking the 'right' questions."

目前對這段話用猜的理解:

"我們已瞭解徵才的不同面向, 現在各位因該也開始知道徵才不僅僅是面試和問正確的問題"

#

後面那句" you may be backing a loser",是什麼意思?

"(You can also check that they have a lot of experience.., that they've done the sort of tasks that you want them to do in your office already, in a similar environment.) But if they start work and you realise that they just don't get along with everybody else, that... say, they've got sharply contrasting views on how something will work.., well, with the best will in the world, you may be backing a loser."

我只能理解前半段大約是:

"但他開始工作後,你發現他無法和同事好好相處,並和大家意見紛歧"
