First of all, if the hiring managers are going to judge a candidate based solely on how they answer the written assessments, then I can assure them that they will be missing out tons of exceptional candidates out there, who may not have the so called "flawless" English language skills, but can offer tons of experience when it comes to handling irate customers, delivering great customer experience to your customers, grow together with your company. After all, isn't this what you are looking for in the first place? Passionate customer experience specialist who not only care about the well being of their customers, but are also willing to go the extra mile in providing the best customer service as well, not to mention add value to the company by challenging themselves professionally by taking on new challenges? Then again, if you believe that judging someone based on how "flawless" their written assessment can be, then by all means go ahead. Its a shame, as I would have been more than happy to grow together with you. But its your loss, and another company's gain
