This is the first line of the cover letter CareersBooster came up with: Over the course of my career, I have always been passionate of working as a Financial Analyst at the International Finance Corporation (IFC).
Passionate of? That's not even correct grammar. And as an opening line that's weak and trite. No way that would ever impress anyone let alone a recruiter at IFC. And the rest of the letter is equally poorly written. Looks like he/she just copied and pasted from an already poorly written letter.
I would not recommend you waste your money on this service at all.
