You see, wanted to apply immediately but saw that you require a cover letter. Now I have to postpone applying, wait until I write a nice cover letter. Meanwhile, I continue applying and interview processes with those companies who required only CV and responded promptly. I might never get back to your company at all. That's the cost of the friction in your application process.
