Do: Research the company that you desire to work for
In advance to you applying for a job, always search for relevant information pertaining to the company so you can highlight your abilities that will best correspond to their needs. Take a look at the company's "About Us" page, search for recent press releases, and visit their social media pages.
Do: Allow your resume to remain short and simple
Most hiring managers are often swamped with tons of applications and allegedly an average of six seconds will be used on scanning your resume or job application. If you want to increase the probability of staying out of the rejection pile: minimize the phrasing to a minimum and use keywords from the job description so it's obvious at first (very brief!) glance that you're qualified.
Do: Make adjustments to your online presence
Hiring managers are constantly viewing candidates on social media and other online sites. Before you job hunt, make certain that there aren't any possible red flags contrary to you being online, such as explicit/ inappropriate pictures or posts. Remove any items you think could portray you in a bad point of view, but don't remove all traces of personality - employers like to see your hobbies and interests to get a feel for how you'd fit into company culture.
Don't: surrender anything without proofreading
Be alert and aware of any correspondence that you have with a possible employer - from the opening application to any follow-up emails. Each one is an chance to display your communication skills and concentration to detail. Even just a instant reply to an email can make you look flawed if you submit it with a typo.
