I have accepted a new job at a particular company. The company has casual attire (Jeans, T-Shirt). I have even seen some people wearing shorts (I would pass on that!).
Since, I will be joining as a new employee how I should be dressed for 2-3 months. Should I still wear formal attire (full sleeves with dress pants).
Also, how can I make a good impression as a new employee? I will be in a senior level position and I will be responsible for training other employees on certain technology.
