Since, students go through the similar coursework and classes for all the programs.
How will the professional recruiters know which one you have attended? Will there be a mention about the format (online/part-time/full-time) in the degree certificate?
The two advice-givers above are wrong, in that they're giving unconditional advice, when in fact the reality is far more nuanced (at least as it regards programs in the USA).
The truth is that the answer to your question will vary from school to school -- however -- my research indicates to me that most of the top schools offer an MBA degree through several platforms -- full-time, weekend, nights, executive and/or online. The certificate doesn't delineate the method of learning. The only ways someone might be able to figure it out is (i) by the dates attended on your resume (i.e., if you attended longer than 18-22 months, it wasn't a FT program, but if you do attend 18-22 months, there's no guarantee it actually was a FT program) ... or ... (ii) asking the applicant about their experience in the program ... or ... (iii) asking other students they know are / were FT about whether or not they knew you.
Lower-tier schools may actually state on their diploma that it's an "evening and weekend MBA" or "online MBA" or "executive MBA" ... but, I'd doubt that's not the norm, but an exception.
Good luck to you.
