3. What are your job responsibilities?

I work in…

With this phrase, you can talk about two different things about your work.

• 
  The fields of work you are in
  
• 
  The department in your company you work in
  

So if you were talking about the field of work you are in, you could say one of the following:

• 
  I work in advertising
  
• 
  I work in sales
  
• 
  I work in agriculture
  
• 
  I work in the fashion industry
  
• 
  I work in the tech industry
  

The field is the general area of work that you are in. You are usually trained or educated to work in this field.
But you can also use this phrase to talk about the department where you work:

• 
  I work in the sales department in a car company
  
• 
  I work in the marketing department of a cosmetics company
  
• 
  I work in the design department of a sports company
  

When using the phrase this way, you usually have to say what type of company it is.

I’m in…

Sometimes, people just use a more simple expression:

• 
  I’m in sales
  
• 
  I’m in marketing
  
• 
  I’m in design
  
• 
  I’m in education
  

This is the same meaning as saying I work in but in shorter form.
