1. I work in that building across the street.

2. I am a computer programmer/ a computer scientist.

3. I am a banker/ bank clerk / bank employee / teller /

4. I am an information provider.

5. I am a prosecutor.

6. I am a lawyer/attorney. (Are both the same? Which one is popular?)

----------------------------
I wrote down some sentences. Would you check them? Are the job-related expressions are all correct?

All look good except for #4. It's pretty general. Alternatives might be ...

I am a concierge in the hotel.
I am a receptionist.
I am a reporter.
etc.

Lawyer and attorney are about the same thing. I hear them used interchangeably all the time.

Yes, I can help you check your sentences and clarify any job-related expressions that may need correction or further explanation. Let's take a look at each sentence one by one:

1. "I work in that building across the street." This sentence is grammatically correct and does not contain any job-related expressions.

2. "I am a computer programmer/a computer scientist." Both expressions are correct and refer to different roles within the field of computing. A computer programmer specializes in writing and implementing code, while a computer scientist focuses on the theoretical and algorithmic aspects of computing.

3. "I am a banker/bank clerk/bank employee/teller." These expressions are all correct and refer to various roles within the banking industry. A banker can have a broader range of responsibilities, while a bank clerk typically assists customers with administrative tasks. A teller specifically deals with handling financial transactions.

4. "I am an information provider." This expression is also correct. An information provider generally refers to someone who offers information or knowledge to others, which could be in different contexts such as a librarian, researcher, or online content creator.

5. "I am a prosecutor." This sentence is grammatically correct. A prosecutor is a lawyer who represents the state or government in criminal cases, presenting evidence against individuals accused of committing crimes.

6. "I am a lawyer/attorney." Both terms, lawyer and attorney, generally refer to the same profession and can often be used interchangeably. However, in some jurisdictions, attorney may have a narrower legal meaning, specifically referring to someone who has been authorized to act on behalf of another person in legal matters. Lawyer is the more commonly used term when referring to legal professionals in general.

Overall, your job-related expressions are correct, but it's always a good idea to consider specific job titles or roles based on the context in which they are used.
