This situation is normal. After all, in the eyes of many companies, the human resources department is almost unnecessary for the company. So don't go to the company to waste, but you do have more important things at the moment.
On the other hand, the company did not conduct pre-job training, and did not clearly inform the specific provisions for training and teaching employees. During the training and induction, there is no requirement to take part in study, training or even pre-employment tests.
The company hopes to get to know and adapt to each other before establishing a relationship with you, so that both sides can avoid wasting time because of mutual understanding. The company wants to have a company culture before joining the company. After all, the people who finally entered the company must have been recognized by some "smart" people. Employees facing learning in the company will naturally not miss the opportunity to promote the company. Authorized personnel will be more skilled in business. In the induction education, let employees know the company's development history, outstanding performance and product positioning.
Some jobs really need a little time to study, usually three or two days. If the time is too long, you should get a basic salary. These three or two days are also for you to adapt to the company, of course, this is not absolute. Some companies will give basic salary, while others will not. I think this is normal, mainly depending on whether they can accept it. You can also use the time of induction study to complete it.
The purpose of inviting new employees for induction education is to familiarize them with the company, recognize the company and achieve the purpose of integration. But if you don't do induction education, I still hope you can experience the working environment, working atmosphere and what kind of company I personally choose in your new position. Choosing a job is also a big problem in life. Be careful when you really choose, and don't enter a bad and inactive company at will.
