Being extra prepared for any interview or even in the application process is always really important. always should make sure that someone proof reads their cover letter before sending it in as well. how can this ?

This can help in different ways, one being that words you may have thought you have spelt write may be wrong or the context, tone or how the words read may not be very good or easy to understand. This will also help to have clean eyes on the work that haven't seen it before, these can offer advice and judgement on things tht should or shouldn't be in there,

Sorry man that a really hard one you got there
