I will write a review of the course "Sales Tricks." This is truly essential training for sales managers. They teach skills for handling cold calls and personal meetings, help with overcoming objections, negotiating, and closing the deal, as well as introducing the basics of profiling. Overall, these are real tricks in sales. The course came with a free knowledge base, which included checklists, instructions, Excel templates, and various cheat sheets. I took the training with colleagues (it was corporate training, sent by my job), and this is the first professional development course where I actually gained useful knowledge, not just a certificate. Now I apply this knowledge in my work with clients and am already seeing positive results.
