That can be solved with spell check + internet. I actually recently sent off an application where i put "replay" instead of "reply" and still got a call back lol, i like to believe most people understand one silly mistake as we are all human. But yeah definitely need to proof read that shit because we all make stupid mistakes and if its really bad it can make you memorable in the wrong way.
If you dont have any good references you may want to work somewhere basic for a few months like a grocery store or something people like work history but also progression it says a lot to show a forward progression. So like grocery store for 6 months start applying somewhere a little better and you even get to say "i have big plans in my life and i need a job to fulfill goals, i started small because i
needed a job but now i have come to realize i need something better then where i am" Sounds better if the place you are applying for is a bit less then basic. Just a thought
