Gain a lot of knowledge and experience.The good thingsThe environment and my leader "Don't talk bad about others/colleague/team", "Teamwork is the most important", "Good environment will make you wake up in the morning in a good mood to come to work", "toxic people will make the teamwork worst", "Be a leader, not a boss" - I enter the company with nothing, and grow into something today because those principle.
The challengesThere's no hard challenges when work together as a team and all equal. The hard challenges come when the teamwork broke.
