If you have ever been job hunting, you know how frustrating the application process can be. You spend hours looking for positions and writing customized applications to impress the recruiters and hiring managers. You dedicate all that time and get your hopes up only to receive an automated "thank you, but no thank you" email or, in many cases, no response at all. You feel disappointed because you were so sure that you were the right person for that job.
Anyone who has ever posted a job advertisement knows that the majority of the received applications are not going to fit the role. Some are too junior, some way too senior, some don't mention the basic skills required for the job, and some don't meet any standards of a well-written job application. Also, if you have ever done this, you know how extremely time-consuming it is to screen 200+ applications.
