It is not easy to become a management trainee, especially in some big companies, because the purpose of recruiting management trainees in these companies is to train future managers, and they will pay great attention to your practical ability and leadership ability. The written interview is still very difficult. You will be tested for some intellectual problems, and then there will be a group interview to see if you can shine.
On the other hand, this position is the hottest among all positions, even hotter than full-time, and you will have quite a few competitors.
Even if you beat all your competitors, it doesn't mean that you can stay successfully in the end. The elimination rate of management trainees is very high. Perhaps after two years of training, it is very likely that the company is unwilling to keep people.
Finally, management trainees generally only need fresh graduates or people who have worked for less than two years.
This position is very challenging. If you have confidence in yourself, you might as well have a try.
To supplement your question, March and April are the climax of recruitment every year, because many employees resigned at that time, so it was a routine to recruit people at that time, but the situation of each company was different. If you really want to go to the company you mentioned, you must pay attention to their official website and see if there are any acquaintances in that company. Foreign companies actually value relationships. Many foreign companies let internal employees introduce themselves. Not through recruitment, because it is more targeted, and the company also likes well-connected employees. See if there are any brothers or sisters and try to find them. I hope I can help you.
