總結(jié):
關(guān)于項(xiàng)目
在就是你項(xiàng)目經(jīng)驗(yàn)，一定要突出你遇到什么難點(diǎn)，然后是怎么解決的!把問(wèn)題引導(dǎo)到你熟悉的領(lǐng)域,或者知識(shí)點(diǎn)上,盡量將每個(gè)技術(shù)點(diǎn)細(xì)節(jié)凸顯出來(lái)，
心態(tài):
什么樣的面試官都有，去面試的時(shí)候要做好一切心理準(zhǔn)備，不管是技術(shù)還是基礎(chǔ)都得扎實(shí)。一個(gè)人的交談能力也很重要，總之不是非常標(biāo)準(zhǔn)的普通話， 最起碼你說(shuō)的得讓別人聽得懂，而且得把面試官講得非常徹底，這樣你獲得offer的機(jī)會(huì)更大，談工資也有優(yōu)勢(shì)~~
