Wow, that thumbs down ratio, one of my biggest ever.
The amount of people who don't seem to understand the point in this video is quite staggering
You'd be more popular with a video of you kicking a dog than criticizing poor spelling!
Of course everyone makes mistakes, but a resume for a job application is the only thing most employers ever see or know about an applicant. Employers expect that applicants will put more effort into their resume than a text message, informal email, or blog post. Poor spelling, grammar, or formatting in a resume show inattention to detail. Yes, writing a resume may be boring and tedious, but much of the work of an engineer can be boring and tedious, but it still requires great attention to detail to get right.
No, you don't need to be able to flawlessly spell every word without assistance, but you should be able to use a spell checker and proofread your resume, which is the sole artifact that you will be judged on initially!
Employers have limited time and tens to hundreds of applications to evaluate. When looking through resumes, employers are looking for reasons to eliminate applicants. They don't have time to spend on 1-2 hour interviews with every applicant, and they don't have time to hire every applicant for several months to see if they can do the job, even if they can't write a resume or have no experience.
Applicants should not expect employers to find reasons to hire them. Applicants must demonstrate that they are better suited to the job than all the other applicants out there.
An applicant going in with the attitude that "I'm so obviously good, I don't need to worry about irrelevant details" shouldn't expect much success.
