Agood time to observe the dress code to prepare for your first day is during
a. your interview
b. your second day
c. your orientation
d. the weekend

I will choose letter a. interview.  This is when you will make the most impression when you are applying for the job.  If you come with full business attire and well-groomed then it is a sign that you are serious about applying for the position.

a. your interview

Explanation:

The dress code is an important signal about the company profile. That's why it's important that you fit this code. Ideally, you should research even before the interview. However, during the interview you will have access to some of the company's employees. This is the key moment when you can see live how these people dress and behave within the company. This way you can make your company debut in a way that adheres to the dress code.
