How to get familiar with the company's products quickly?

Our company's method is as follows: \x0d\ (1) introduces the products one by one with the company's product catalogue, and gives the new employee a product catalogue (for his own use) so that he can write down the product parameters or features that are not introduced in the catalogue at any time; This is an oral introduction. Although the employees had heard the relevant product introductions at that time, they forgot to use them in the future. \x0d\ (2) Arrange him to upload the products to online stores such as Ali Wangpu and Taobao Mall, so that he can not only learn about the products from the product pictures, but also upload the product descriptions and parameters, so as to deepen the understanding of the products for new employees; \x0d\ The time above is about one month; \x0d\ (3) Arrange him to practice in the workshop and delivery department of the factory, so that he can really get in touch with the products, ask the workers or technicians at any time if he doesn't understand anything, and have a basic understanding of the production situation and goods links (lest he blindly take orders). Of course, he must also receive customers at any time and communicate with customers by telephone or network; This internship period is about one month; \x0d\ Our requirement for new employees in charge of business is that the first three months are internship period, and that's the basic internship content (we have two factories). Through this at least three-month internship, if new employees can persist and perform well during the internship, these people are basically the backbone of the company now.
