What are common and simple mistakes that can result in losing an opportunity to interview for a position?

What will be an ideal response?

While you're making all these positive moves to show employers you will be a quality hire, take care to avoid the simple blunders that can torpedo a job search, such as not catching mistakes in your résumé, misspelling the name of a manager you're writing to, showing up late for an interview, tweeting something unprofessional, failing to complete application forms correctly, asking for information that you can easily find yourself on a company's website, or making any other error that could flag you as someone who is careless or disrespectful. Assume that every employer will conduct an online search on you. Busy recruiters will seize on these errors as a way to narrow the list of candidates they need to spend time on, so don't give them a reason to toss out your résumé.
