Always remember that your online application needs to be both professional and presentable. It doesn’t even matter how often your resume shows up for typos or grammatical errors. First, It is as easy as being able to communicate professionally with your contacts – the people who communicate with you and vice-versa. It you wanted to send email or IM to your contacts, make sure they are done properly and consider those as formal business correspondence. Lastly, keep note of the sites where you posted your resume and profile (a password list too), that way you can update your profile and be updated with your information.
