The applicant screening process should ideally take as little time as possible, as companies can easily spend too much time and money on hiring. To reduce these costs and time wasted, it’s important for hiring managers to be able to quickly recognize the difference between a good and bad candidate. Unfortunately, differentiating between potentially good and bad hires isn’t as easy as scanning a resume. Here are a few warning signs to look out for during recruitment:

Subpar communication
In almost every position, some high level of communication will be required, and during the application process, recruiters should expect high caliber interactions. When communicating with potential employers, it should be expected that candidates review emails and messages before sending them. Individuals should read through email communications they are sending to hiring managers to make sure they are free of spelling and grammatical errors, and should use always professional language. There’s no room for shorthand in these communications, TLNT reported.

TLNT reported unprofessional communications are a red flag for hiring managers because poor communication speaks to the possibility of laziness or a level of disrespect on the part of the applicant. Another reason to avoid candidates who send emails riddled with errors is that these communications may reflect how they will handle client communications if they were to be hired.

Despite the fact that job seekers are actively trying to woo a company into hiring them, many hiring managers occasionally come across candidates who are rude or abrasive. If a candidate comes off as demanding by sending several forceful emails asking about the position after an interview, recruiters should be wary. The same is true if candidates are pushy, use any sort of insulting language or treat other members of a company with anything less than true respect.

For example, many hiring managers make a point to ask administrative assistants or receptionists how a candidate interacted with them when they arrived for their interview. Recruiters should take note of these behaviors – being rude to a receptionist, making demands or generally acting in an unkind way points toward a habit of behaving similarly in other situations. If a candidate is rude, it’s time to move on to the next applicant.

Arriving late and delaying communications
One of the most common tips for job seekers is to arrive early to an interview, so there’s really no excuse for not showing up on time for this important part of the talent screening process. While some circumstances are beyond the control of a candidate – trains breaking down, for example – delayed communications should always be a warning sign. If a candidate says they plan on sending writing samples or their resume to a recruiter on a certain day, and they do not carry through on this promise for another 48 hours, it’s probably best to move on to a different applicant.
