Do I need to use the word "scheduled" if the time is specified?

[Zoli]

My name is Zoltan, and I have an interview scheduled at 2 p.m.

or I can just go with:

My name is Zoltan, and I have an interview at 2 p.m.

Context:
The time is specified, so I think it's obvious that the interview is scheduled.
This phrase is used with the receptionist when going to a job interview.

oOr I can I just go with:

My name is Zoltan, and I have an interview at 2 p.m.?

Yes, you can.

Should I say "My name is Zoltan, and I have an interview scheduled at 2 p.m." or can I can just go with no colon here "My name is Zoltan, and I have an interview at 2 p.m."?

Context:
The time is specified, so I think it's obvious that the interview is scheduled. This phrase is to be used with the receptionist when going to a job interview.

The second suffices.

This may be off-topic but instead of "p.m" is it possible to use "o'clock"?

My name is Zoltan, and I have an interview at 2 o'clock.

Yes, it is, if it is obvious that you mean 2 pm.

 

[emsr2d2]

Given that you're likely to arrive for the interview at around 1.50pm for a 2pm interview, there's no danger of the receptionist thinking you mean 2am if you say "two o'clock"! In fact, it's highly unlikely that anyone would ever think you have an interview at 2am!

Depending on how formal you want to be (I get the impression you're not being too formal on the basis that you're only giving your first name), you could just say "I've got an interview at two".

There are some situations where you need to specify "am" or "pm". If you're talking about a flight landing at 6 o'clock, it could be either.

Often it's obvious, as emsr2d2 says. If you say "I wake up at 6 every day", you don't need to specify "am", unless you work a night shift.
